I() notation in ReadNetCDF()
subset.ReadNetCDF() now supports cdo operations via the
rcdo package. You can pass an rcdo operation and it will be
executed.
ReadNetCDF() gains support for reading data from
multiple files potentially in parallel.
ResidLm() now returns a vector with NAs.ReadNetCDF() with subset used to return the data based
on the coordinate closest to the subset dimensions. This mean that
subset = list(lat = c(-90, -20)) could return data north of
20°S if the gridpoint north of 20°S was closer to 20°S than the
gridpoint South of it. While not a problem in general, this could fail
catastrophically if the file didn’t have data inside the requested
range. This now is fixed to that it returns only data inside the desired
range.geom_streamline() will replace missing values with
zeroes.ParseNetCDFtime() to quickly parse netCDF time
axes.ReadNetCDF() now uses the CFtime package to parse
times. This shouldn’t lead to any braking changes, but times are weird
and anything can happen. Please report anything amiss.
Contour breaks are now computed after scale transformation. Previously they were computed using the whole dataset, which could lead to nonsensical contour breaks if scale limits removed extreme values.
ReadNetCDF() can now subset based on dimension indices
instead of dimension values. This makes it possible to read “the first
10 timesteps” or “the last 10 timesteps” without needing to know which
dates they correspond to and how many timesteps are in total.trans/transform argument.EOF()’s rotate argument now will take a
function to apply to the EOF loadings. rotate = TRUE is
still supported but deprecated and will default to using
function(x) stats::varimax(x, normalize = FALSE).
Contour functions gain a proj.latlon to decide if
the projection needs to go to latlon coordinates or to projected
coordinates.
GetSMNData() function is defunct. The functionality
was a hack and hard to maintain and it’s also very specific and should
be out of scope for a general package.trans argument of scales has been renamed to
transform following ggplot2’s change.scale_mag() internals are now much simpler and inherits
all the functionality from common continuous scales. (thanks @teunbrand for the
suggestion, #186)step computed variable in
geom_streamline() now goes from 0 to the total number of
steps instead of from negative half to positive half.clip argument to only show
contours in an area defined by a polygon.kriging argument of the contour functions now can
be a numeric to control de number of pixels used.FitWave() and friends improved (#184,
@pascaloettli).proj argument in geom_contour_fill()
and friends now operate over the isolines returned by the isoband
package. This might break code that used a custom function to
proj.DivideTimeseries() function is now defunct.FitLm() gains a new intercept argument
that allows you to remove the intercept term that is automatically
added.Laplacian() when computing the laplacian
of a single variable. (#170, Thanks @pascaloettli)geom_relief() and
geom_shadow() now don’t have a size aesthetic, since they
shouldn’t have had it anyway.scale_mag() is now chosen to be a “pretty” number close to
the maximum. This will prevent guides with many unnecesary decimal
places (thanks, @PanfengZhang #161).expand value in
sale_x_longitude() and friends (thanks, @tamas-ferenci,
#167).Smooth2D() smooths a 2D field (hence
the name). There are two smoothing methods. smooth_svd()
computes the SVD of the field and reconstructs it keeping only the
leading values that ensures a maximum variance lost.
smooth_dct() computes the Discrete Cosine Transform of the
field and sets a proportion of the components to zero.Fixed a bug in geom_streamline() when plotting
multiple fields on the same panel.
Fixes a bug with GetTopography() on
Windows.
Updates documentation to use valid HTML5 per CRAN’s new format.
Fixes the “The following aesthetics were dropped during statistical transformation” warning for contours.
Removes ReadNetCDF() file and URL checking because
it didn’t work in some cases. (#164, thanks @pascaloettli)
ReadNetCDF() not longer uses it to parse dates and times.
The homebrewed parser might be more limited, and the wild variety of
netCDF files in the wild makes it hard to fully test. Please report any
issues you have!Adds example of scale_y_level() (@paocorrales,
#153).
ReadNetCDF() now should parse times correctly even
if the use non-standard calendars. This now makes udunits2 and PCICt
required to parse time.
Arrays returned by ReadNetCDF(…, out = "array") gain
a “dimvalues” attribute which is analogous to dimnames but has the
correct types (dates are dates, numerics are numerics, etc…).
EOF() gains a new engine argument to
chose the function to compute the singular value decomposition.
sdev component in EOF() when
using base::svd() in some cases.seasonally() now returns a Date object even if the
input is datetime. This avoids issues when the time component of the
input was not all the same.ImputeEOF() in which the algorithm tried
to compute 0 EOFs.geom_contour2() gains the ability to draw –and leave
space for– labels! This is finally proper labelling support without
having to use a different geom (geom_text_contour()).
Thanks to the isoband package for this.
Following isoband’s
naming convention, the family of functions that decide where to
place labels has been renamed as label_placer_ and the
corresponding argument is now label.placer . The
label_placement_ family of functions will be deprecated in
future releases.
discretised scales now work better when passing user-supplied limits.
New functions to use the International Standard Atmosphere to get
height from pressure and vice versa, as well as to use as secondary
axis. See ?standard_atmosphere.
scale_y_level() and scale_x_level() now
print more breaks by default. These functions will probably use this
transformation instead of the reverse log transformation in a future
release.
Translation! Thanks to @MichaelChirico priceless guidance, metR messages are now translatable and already translated to Spanish. If you are using R in a Spanish locale you should be getting messages and error in Spanish. Partial translation to Portuguese is also included.
During the process of translating messages, many messages were improved and made more consistent.
New Function ResidLm() that returns the residuals of
a linear fit.
New function Detrend() that, you guessed it, returns
a (linearly) detrended version of the input vector.
In ReadNetCDF(), the “vars” argument now can take a
function. (#142)
Discretised scales now support user-defined breaks.
seasonally() result will be on the 15th of the centre
month of each season instead of on the 1st. This makes the date more
representative of the time span and also solves a bug in which dates on
the 31st would return NA. This is a potentially
breaking change.ReadNetCDF() doesn’t fail when reading variables with
no dimensions (thanks to @paocorrales, #141).geom_contour_tanaka() in R >=
4.1.0.as.discretised_scale() is a quick way of created a
discretised version of any continuous scale.
stroke.colour is now an accepted aesthetic for
geom_text_contour().
The computations in MixingRatio() were wrong. Now
they are fixed.
I really wanted geom_arrow() to automatically add
the arrow legend, but the workarounds I managed to write were brittle
and couldn’t handle even slight changes in people’s code (see https://github.com/eliocamp/metR/issues/130). The
definitive answer is that this is simply not possible due to limitations
on how ggplot2 works (see https://github.com/tidyverse/ggplot2/issues/4291). This
release, then, backtracks those workarounds and tries to accept the
things I cannot change.
I’m very happy with discretised_scale(), which is a
type of scale which takes a discrete values that are the result of some
discretisation and treats them as continuous. It’s, in a sense, the
inverse of the new ggplot2::binned_scale(). Whereas.
ggplot2::binned_scale() takes continuous values and then
discretises them, discretised_scale() takes discrete values
which where the result of some discretisation procedure (such as the
levels of
geom_contour_fill()/ggplot2::geom_contour_filled())
and allows you to treat them as continuous.
Related to that, geom_contour_fill() now gains a new
computed aesthetic called level_d, which is the same as
level but forces ggplot2 to automatically use the new
discretised scale.
AnchorBreaks() gains a bins argument to
mimic the default functionality of MakeBreaks().
New label_placement_minmax() to label contours at
the maximum and minimum points of a contour (mimicking isoband’s
behaviour)
geom_contour_tanaka() now has a (rather
experimental) argument smooth which allows to smooth the
transition between segments.
Fixes error introduced in previous version when
geom_arrow() had mappings other than dx and
dy. (Thanks Santiago!)
The level derived aesthetic from
geom_contour_fill() now returns and ordered factor with the
correct labels that can be interpreted by
ggplot2::guide_colorsteps(). This might a breaking
change!
geom_label_contour() lives! The previous release
rewrote much of the way geom_text_contour() worked, but I
messed up and didn’t realised that the new code had broken
geom_label_contour() (to be honest, I’d almost totally
forgotten about it :P). (fixes #126, thanks @kongdd)
geom_text_contour() placement of labels is
completely redesigned. It gains an argument label.placement
which takes a function that is in charge of positioning the labels. See
label_placement_flattest() for more details on the possible
placement methods and how to build your own. The default method is
label_placement_flattest, which places the label where the
product of the curvature and the angle of the contour is minimised. This
aims to put labels in a straight segment that is also as horizontal as
possible. If more than one point satisfy this condition, then it chooses
the closest to the midpoint. This is a breaking change,
as it will change the label position of previous plots.
The contour functions also gain a proj argument. It
can be a proj4 string to project the contours of or an arbitrary
function to alter the contours after they are computed. This now makes
it possible to compute contours for data that is on a regular grid on
projected coordinates but want to plot in lon-lat coordinates (or vice
versa). Bear in mind that contours that cross the dateline will probably
end up mangled.
Contour functions also gain a kriging argument. If
TRUE, will perform ordinary kriging to interpolate
irregularly placed data into a regular grid.
FitLm() handles NAs better.
GetSMNData returns the date parameter
with the correct time zone.
WaveFlux() now only returns the value of the
horizontal fluxes. That is, it will not return lon and lat. This
is a potentially breaking change.
The contour family of functions now use isoband to
compute contours (thanks to @clauswilke for the awesome package)
instead of my ugly hack/workaround. As a result, contours are faster and
much more reliable.
EOF() will now work even if {irlba} is not
installed.
GetTopography() is now updated to the new ETOPO
server. It now requires {raster} to work.
FitWave() and related functions return
NAs when the inputted signal has NAs.
FitLm() accepts a weights argument to
perform weighted regression.
ReadNetCDF() now can read files directly from DAP
servers and other urls, and objects returned by \[ncdf4::nc_open()\].
ReadNetCDF() won’t try to parse “time” dimensions that
are not dates and will try to parse as time all dimensions.seasonaly() is now correctly called
seasonally(). This proves that you don’t put an ESL person
in charge of naming stuff.EPflux() computes Eliassen-Palm fluxes
(experimental).
geom_arrow() and geom_vector() should
plot faster.
New functions is.full_season() and
seasonaly().
FitLm() returns model \(r^2\) and adjusted \(r^2\).
FitLm() adds names to unnamed terms.
New function WaveEnvelope() that computes… the wave
envelope.
geom_contour2(), geom_contour_fill()
and geom_text_contour() now accept a
global.breaks argument that controls whether breaks should
be computed once using the range of the whole dataset or once for every
grouping (e.g. faceting). TRUE (the default) ensures that
intervals between contours are comparable between panels. Setting it to
FALSE computes contours compatible with
ggplot2::geom_conotur() (#109, thanks @freeseek)
A reworked non-equispaced derivative gives better results in
Derivate().
ReadNetCDF() will not fail if the first variable was
called “v” (yeah, I know.. weird error related to data.table’s non
standard evaluation).
Subsets in ReadNetCDF() won’t fail if no element is
named (#107, thanks @m-saenger)
Fixed bug in WaveFlux() (#110, thanks @salvatirehbein)
ReadNetCDF() supports using NA in
subset to refer to max or min value.
ReadNetCDF()’s subset argument supports more complex
queries. (see the help section at?ReadNetCDF()).
ReadNetCDF() now has a simple date-time parser that
is tried if the udunits2 package is not installed.
GetSMNData() gains the ability to cache results in a
file.
Derivate() now can derive in a non-equispaced
grid.
geom_contour_fill() imputation method is fixed for
some special cases (#96; thanks @bergmul).
predict.eof() handles complex value svd
correctly.
Accommodates new grid implementation of units (#105 thanks @pmur002).
New GlanceNetCDF() function that is an alias for
ReadNetCDF(out = "vars") but now prints a human readable
summary of the contents of the NetCDF file.
geom_streamline() now uses 4th order Runge-Kutta
instead of plain old Euler. It also draws arrows in the middle of the
streamline.
ReadNetCDF() is slightly faster and should use less
memory.
ReadNetCDF() supports more complex subsetting
operations now.
The df element returned by FitLm() now
has the same length as the rest.
ReadNetCDF() result will print correctly.Anomaly() has a new baseline
argument.
New function Trajectory() that computes trajectories
in time-varying velocity fields.
ReadNetCDF() now accepts dates as elements for
subset.
ReadNetCDF() will read all dates correctly (#91;
thanks to @m-saenger).
The es argument from MixingRatio()
changes to e, to be consistent with the rest of the
variables. Sorry, thermodynamics is not my forte! (thanks @PaoCorrales)
Arrow heads in geom_arrow() are now scaled correctly
in faceted plots (fixes, #92; thanks to @m-saenger)
There has been some changes in the interface of some functions for the sake of consistency.
In Derivate() (and it’s derived functions –see what
I did there?), the data argument has been moved back. This
is because this function is intended to be called inside a
data.table of mutate() call, where you don’t
need to explicitly specify the data.
In EOF() the dcast-style formula interface has been
removed. The data argument was also moved back so you can
use the n argument more easily without naming it.
ImputeEOF() follows the same conventions. The
dcast-style interface has been removed and the data
argument has been moved after the max.eof
argument.
BuildQsWave() and FitQsWave() have been
removed and should had never even existed.
The default skip argument for
geom_text_contour() is now 0.
Removed hemisphere argument from
season() since the function returns the trimester so it
made no sense.
Contour functions now compute breaks globally (using all the
data) instead of per panel. This means default intercomparabilty between
faceted plots but also a considerable deviation from
ggplot2::geom_contour().
The Between operators are removed since they were
already implemented in data.table.
The default geom for stat_na() is
changed to point for consistency with
stat_subset()
geom_arrow() and geom_vector()
scale with vector magnitude.geom_streamline() for visualizing vector
fields.dlon(), dlat(),
dx(), dy() for converting physical units into
spherical units.geom_contour_tanaka() that plots illuminated
contours.Interpolate() for bilinear
interpolation.FitWave() with wavenumber 0. Now it
returns the mean.FitWave() runs slightly faster and
BuildWave() runs much faster.GeomContourFill object since it was just a
polygon.EOF() now use factors instead of
numbers to identify each PCscale_mag() and guide
guide_vector() for controlling and communicating the scale
of vectors. These are highly experimental and will
change in the future, but provide some very needed functionality so I
decided to export them as they are.geom_arrow() gains new pivot argument to
control point of rotation and preserve.dir to tell if angle
should be preserved.stat_contour_fill() and stat_contour2()
print a warning when no contours can be made.EOF() now supports estimation of confidence intervals
via bootstrap.EOF() supports varimax rotation. Rotated components are
labelled accordingly.geom_relief() is much faster now (but see package
rayshader).geom_shadow() for casting shadows in topographic
maps.StatContour2 are memoised so they are only
computed once even adding several layers with the same contours
(geom_contour() + geom_text_contour()) or running the same
plot while tweaking it’s appearance.FitLm() for getting fast estimates of linear
fits.FilterWave() for filtering waves.RepeatCircular() was deprecated in favour of
WrapCircular() which is more robust, and then
WrapCircular() was deprecated in favour of the
ggperiodic package.stat_contour2(),
stat_contour_fill() and geom_streamlines()
handle circular dimensions has changed. Now you need to use
xwrap/ywrap to explicitly set the domain. This
makes the implementation more robust and also allow to easily wrap to an
arbitrary domain.ggperiodic, which can handle this stuff better. The above
mentioned arguments still work but are not documented and will be
deprecated.EOF() gains a fill argument for sparse-ish
data.geom_text_contour() now has the ability to draw a
stroke around text.geom_contour_fill() now can impute missing values with
bivariate interpolation.BuildField() actually renamed BuildWave()
(which should’ve happen in the previous release according to this
News).as.path() and added functionality to
Interpolate() that allows to interpolate values along a
path of locations.Impute2D() which is an exported version of
the method used by geom_contour_fill() to (soft) impute
missing values.subset argument in ReadNetCDF() now
accepts character vectors for time components.GetTopography()ReadNetCDF() now can output arrays and vectors.pkgdown.coriolis() and
coriolis.dy().Anomaly() (can’t believe I did that).EOF() principal components are numeric instead of
“PC1”, etc…stat_contour() created
geom_contour_fill() which works just like
stat_contour_fill().stat_na() for easy masking of NA
values.geom_arrow() now is geom_vector() with
better documentation and more parameters and geom_arrow()
is a new geom for arrows that preserve direction.ReadNetCDF() now handles more date formats.Laplacian(), Divercence()
and Vorticity()DerivatePhysical() is removed since it was made
redundant by the extended functionality in Derivate()geom_text_contour() and
geom_label_contour() for labelling contours.GeostrophicWind().ReadNetCDF() and
as.POSIXct.ReadNetCDF() now supports time-zones via de
udunits2 package.stat_contour_fill().MakeBreaks() and
AnchorBreaks().guide_colorstrip() displays discretized
values of a continuous colour or fill scale.stat_contour_fill()geom_relief() for generating relief shading.ReadNetCDF() gains a subset argument for
subsetting data.AnchorBreaks() is a new way of generating breaks.geom_contour2() that takes a function as argument
in breaks and geom_contour_fill() also does
the same.stat_subset() that makes subsetting data on the fly
easier.ReadNetCDF() can return a keyed data.table.FitQsWave() and BuildQsWave() renamed to
FitWave() and BuildWave(), respectively.GetSMNData() is updated to include the new SMN website
and data types.geom_contour2() and geom_contour_fill()
gain a circular argument to specify a circular
dimension.RepeatCircular() renamed to
RepeatCircular().LonLabel() and LatLabel() aid labelling
latitude and longitude.EOF() and
ImputeEOF().
