(2025-08-12) all instances of atan2 revised for producing output in
the format required (between -pi and +pi or between 0 and 2pi, depending
on further usage).
(2025-08-12) missing or mismatch braces in some help pages
corrected.
(2025-08-12) functions from other packages correctly anchored in
helpfiles.
gmGeostats 0.11.3
(2023-04-17) functions producing multiple plots now restore the
graphical parameters to initial state if terminated; minor corrections
to help files; stub vignette “Simulating microstructures with
gmGeostats” is not packaged any more with gmGeostats to CRAN, but can be
found here (until it is finished)
(2023-04-13) batch of hidden methods exported to the namespace
(mostly for as.*() functions converting between different
representations of empirical variograms and of geostatistical
models)
(2023-04-04) C routines called as symbols and not name strings;
non-ASCII characters removed
gmGeostats 0.11.2
(2022-11-22) flag ‘-lstdc++’ removed from makevars.
(2022-11-15) minor bugs in accuracy calculations corrected.
References improved.
(2022-08-15) bug in turning bands for spherical variogram
corrected.
gmGeostats 0.11.1
(2022-05-03) minor changes to adapt to more stringent standards for
class determination, for variable definition in C code, and for calls to
FORTRAN routines from C code involving string arguments.
gmGeostats 0.11.0-9002
(2021-12-14) bugs in turning bands corrected: getUnitVec was
producing a wrong sequence of directions, and bands for exponential and
Gaussian variograms did not correct for the difference between
parametric and effective range in the right way;
(2021-12-08) anisotropy objects complete, restructured and
everywhere correctly used: if class(A)=="AnisotropyScaling"
and class(M)=="AnisotropyRangeMatrix" (the two possible
classes), then A %*% t(A) == solve(M); with them,
u = sqrt(h %*% solve(M, h)) can be used in a scalar
variogram (i.e. M is a matrix of ranges and orientations),
and v = t(A) %*% h an isotropic variogram
(i.e. u=sqrt(sum(v^2)), and A is a scaling
matrix that makes the space isotropic)
(2021-12-08) bugs corrected in gsi.EVario3D()
gmGeostats 0.11.0-9001
(2021-11-05) bugs corrected in internal 2D empirical variogram
function gsi.EVario2D() . First version of 3D internal
variogram function gsi.EVario3D() available. Usage of these
functions is only for specialists foreseen. In the near future a
user-friendlier wrapper will be provided.

of empirical covariance for circular data.

(2021-10-17) dependence from randomFields eliminated
(2021-10-17) consolidated management of predict()
methods for S3 and S4 objects, with the help of the internal function
Predict() (not recommended to use)
gmGeostats 0.10.9-9001
(2021-09-30) minor bug corrected on the way fit_lmc passes its
arguments to surrogate gstat and gmGeostats functions
(2021-10-01) management of predict() methods for S3 and
S4 objects, with the help of the internal function
Predict() (not recommended to use)
gmGeostats 0.10.9
(release of polished 0.10.8.900x dev versions) * minor correction on
C source code for compatibility with clang13
gmGeostats 0.10.8-9001
(2021-07-22) conversion methods between variogram models:
as.gmCgram() methods for “variogramModel” and
“variogramModelList” objects (from package “gstat”)
gmGeostats 0.10.8-9000
(2021-07-15) documented abstract union classes, specifying required
methods for the member classes
gmGeostats 0.10.8
(release of polished 0.10.7.900x dev versions)

new vignette “How to register new layer datatypes”, with a howto
adapt gmGeostats to deal with your very special data type (with an
example for regionalized circular data)
(2021-07-06) new option to extract univariate accuracy() from
multivariate kriging results
NEWS.md and vignettes/gmGeostats.Rmd polished
“predict”-methods for objects of class gmSpatialModel now programmed
with multiple dispatching, to enable further extensions
gmGeostats 0.10.7.9005
(2021-06-30) bugs in xvErrorMeasures() for simulated data
corrected

gmGeostats 0.10.7.9003
(2021-04-08) exported turning bands for direct usage

improved/reimplemented as.logratioVariogram() and
as.logratioVariogramAnisotropy() methods; minor edits at

-> LMCAnisCompo -> variogramModel(List)
(2020-09-18) gsi.gstatCokriging2compo() and
gsi.gstatCokriging2rmult() now work with systems of 3
components resp. 2 variables (systems of 2 components or 1 variable
still fail)
