Added %list_rand% summary option to randomly sort values.
Identified an issue when showlegend=TRUE and there is pruning.
htmlwidgets::sizingPolicy()esoph data
frame would not work properly because of the value of the
agegp variable, 75+. The example now recodes
75+ to 75plus.New parameter, prunebigger, prunes nodes bigger than
specified size. This is particularly useful with pattern trees when
there are a few unusual cases.
Vectorized the sameline parameter, to allow
different behavior for different variables.
New parameter, prefixcount, to format counts
(e.g. N=3).
New parameter hideconstant, is more flexible and
intuitive than showuniform (also more intuitively
named).
Altered vtree to work properly with Quarto.
hideconstant is specified with
prunesmaller and pattern=TRUE.Small changes to the vignette.
Added new parameter thousands to specify separator
(such as “,”) between thousands.
Removed one color palette (RdYlGn) which is not
colorblind-friendly. Also added a new colorblind-friendly palette
(Greys). These palettes were pre-calculated using
RColorBrewer.
Added a single-line information message when the package is loaded in interactive mode.
Added automatic text color (black for lighter-colored nodes, white for lighter-colored nodes).
Added tsummary parameter for targeted
summaries.
Added showuniform parameter (TRUE by default). When
FALSE, variables with no variation are not included.
Added words parameter to allow specification of a
tree without any counts.
Added showrootcount parameter to control whether
count is shown in the root node.
Added the.matrix dataset based on the 3 Matrix
movies.
Added targeted versions of the pruning parameters, namely:
tprune, tkeep, tfollow, and
tprunebelow.
When ImageFileOnly=TRUE, graphics files are now
numbered successively, even when not knitting.
Added justtext parameter so that justification of
the extra text can be different.
Added the following options to summary: %nosort%,
%freqx%, %freqpctx%,
%freqpctx_%.
Fixed a small bug where the %list% summary option
used digits rather than cdigits.
Fixed problem when hideconstant is specified with
prunesmaller and pattern=TRUE.
Variables can now be specified as a formula with no left-hand side.
Added support for generating PDF images.
Added none: and notall: for variable
specifications and summaries (these are the complements of
any: and all:} respectively).
Added prefixes anyx:, nonex:,
allx:, and notallx: where the x
indicates that missing values will be removed.
PNG files are now automatically named vtree001.png,
vtree002.png, etc. (PDF files are named
vtree001.pdf, etc.)
Support was added for embedded variable trees in Sweave.
New trim parameter to support trim feature in the
\includegraphics LaTeX command.
Renamed z parameter to data.
Reorganized parameters in help file and added details.
New parameter showlegendsum to show summary in
legend nodes.
New parameter font to specify font to use.
Extended wildcard matching in variable specifications and summary
specifications to match this*that expressions and
this#that expressions.
Codes for less-than-or-equal and greater-than-or-equal were removed due to rendering issues with DiagrammeRsvg.
Fixed bug when using showlegend=TRUE with
pattern=TRUE or with
check.is.na=TRUE.
Fix by trafficonese for tabPanels.
Variable labels are shown differently: no longer boldface, and also larger (24 point instead of 18 point). (The metrics for boldface font seemed to be not quite right, which sometimes resulted in truncated text.)
Revamped legends.
New sortfill parameter. Specifying
sortfill=TRUE fills nodes with gradient colors in sorted
order according to the node count.
vtree return value now has an info
attribute, which is a nested list that gives the count for each
node
When no summary codes for statistics are specified, a default summary is shown, depending on the type of variable.
New variable prefix i: for “intersections” of
variables
New variable prefixes any: and
all:
New summary codes %range%, %freq%, and
%freqpct%.
New variant summary codes (ending in x to disregard missing values, ending in _ to put on separate lines).
New REDCap variable prefix r: and suffix
@
When vars is not specified, only the root node is
shown. (Previously vtree would try to use as many variables as
possible.)
Added more informative error messages.
Added additional color palettes.
The old stem: and rc: variable
specification and summary prefixes for REDCap checkbox variables are now
deprecated.
The lsplitwidth parameter is now deprecated;
vsplitwidth (for splitting variable names) should be used
instead.
splitwidth now applies to legend nodes as well as
ordinary nodes.
Fixed issue with Shiny where vtree not visible immediately.
Fixed problem with summaries when three or fewer observations are present.
Fixed bug with HTML conversion of labels in legends.
Fixed problem with DOT script when there is no root node.
Fixed bug with variable names showing up white when
fillcolor="white".
Fixed bug with pattern tables when prunesmaller was
specified.
New parameter, just, to specify text
justification.
New parameter, arrowhead, to specify the type of
arrowhead (or none).
Added summary variable specification !=
Sebastian Gatscha added Shiny functionality and the svg-pan-zoom
JavaScript library. The following functions were added:
init_js, inlineCssSetup,
renderVtree, use_svgzoom,
vtreeOutput.
New function svtree uses Shiny
functionality.
Modified outputs of vtree to make it work
better.
Thanks to knitr::asis_output(), calling
vtree from R Markdown when generating a PNG file has been
simplified.
Specifying showvarinnode=TRUE shows variable name in
each node.
When no variable list is specified, vtree reports
included variables, excluded discrete variables, other excluded
variables.
Fixed a bug with missing value nodes.
Fixed problem with return value when running chunk from R Studio.
Fixed a bug that occurred when pattern=TRUE and a
single variable was specified.
Fixed a bug that occurred when showvarnames=FALSE
but labelvar was set.
The keep parameter will not prune missing value
nodes when vp=TRUE.
There is a new summary code, %sum%, to show the sum
of values.
prunesmaller parameter to remove nodes with small
counts.
In variable specifications, * matches multiple
variable name endings and # matches variable names ending
with numeric digits.
When called while knitting an R Markdown document, PNG files are now automatically generated and embedded.
pngknit=FALSE disables PNG generation while
knitting. Returns an htmlwidget instead.
The new function VennTable reformats a pattern table
output by vtree for indicator (0/1) variables.
The new function build.data.frame makes it easy to
create a data frame for use with vtree.
If no variable names are provided, vtree will use,
in order, all of the variables in the data frame.
Multi-variable calculations like x/y can be used in
the argument of the summary parameter.
check.is.na now uses pattern=TRUE by
default.
Changed the meaning of the %node% summary code,
which had previously (and confusingly!) been used to specify the
variable in whose nodes summary information should be shown.
Now %node=n% specifies node n and
%var=v% specifies variable v.
Additional text produced by text or
ttext or summary now starts on the same
line as the number of observations and percentage. In order to put
this text on a new line, it must begin with \n.
When seq=TRUE the first-level nodes are ordered from
least frequent sequence to most frequent sequence. (The same applies for
the new pattern parameter.)
Extensive revisions to the vignette.
pattern parameter for unordered sequences of
variables
ptable parameter to generate pattern tables
Variable specification modifiers: stem: for REDCap
checkboxes, is.na:, variable=value,
variable<value, variable>value,
tri:
choicechecklist parameter: When REDCap checklists
are specified using the stem: syntax, automatically extract
the names of choices and use them as variable names.
%pct% summary code to show percentage (not
frequency)
%listlines% summary code to separate items with a
new line (unlike %list% which uses commas).

variable=value, variable<value,
variable>value
tlabelnode parameter: targeted node labels
ttext parameter: targeted text
New function crosstabToCases to convert
crosstabulated data to a data frame of cases

summaries depending on node contents
retain parameter to specify additional variables
that need to be available to execute the functions in
runsummary
varminwidth, varminheight parameters to
control node sizes for specified variables
varlabelloc parameter to control vertical
justification for nodes of specified variables
This is a major release that incorporates several new features.
Automatic variable coloring using gradients.
More compact display (reduced node separation and tighter margins).
The color of the root node can be specified using the
rootfillcolor parameter.
All missing-value nodes are colored white by default. This can be
changes using the NAfillcolor parameter.
By default, the root node now has no title.
NOTE Display from version 0.1.4 can be obtained
by specifying plain=TRUE. This sets:
variable-specific shades of blue
greater node separation
wider margins
missing-value nodes have the same color (shade of blue) as all other nodes at that level
showlevels is now deprecated. Use
showvarnames instead.
Legends, with marginal frequencies and percentages.
To put node labels on the same line as frequencies and
percentages, specify sameline=TRUE.
A new parameter, squeeze takes a value between 0 and
1, and controls how the tightly-packed the display is.
“Sequences” of variables can be displayed by specifying
seq=TRUE.
Additional summary codes: %node=n% to
show summary information only in specified node. %trunc=n%
to truncate the summary to the first n characters.
Settings for multi-way intersections can be specified with
Venn=TRUE.
graphattr, nodeattr, and
edgeattr parameters allow additional Graphviz attributes to
be set.
Other new parameters: palette,
gradient, revgradient,
singlecolor, showpct, showlpct,
showcount, varnamepointsize,
lsplitwidth, margin, showempty,
prunelone
