improved handling of parallelized matrix multiplications and parallelized computations of generalized covariances by main process and and child processes running already in parallel
code file georob_private_functions.R replaced by 4 new code files georob_private_further_functions.R, georob_private_generalized_covariances.R, georob_private_georob_fit.R and georob_private_psi_functions_etc.R
minor edits in various help pages
minor revision of vignette
substituted all donttest statements in examples with
lengthy computations by interactive() clause which has the effect
that lenghty computations are only carried out in interactive
sessions
correction of error in predict.georob() when processing
output
plot.sample.variogram() now returns NULL
eliminated lonely item in NEWS.Rd
eliminated dependency on functions RFfctn() and
RFsimulate() of archived package RandomFields by new
functions gencorr(), sim.chol.decomp(),
sim.circulant.embedding()
added on.exit(options(oldoptions)) and
on.exit(par(oldpar)) after call options() and
par() in function code
querying class attribute by inherits()
changed default for argument allow.recursive of function
control.pcmp()
more efficient calculation of lag.vectors for
geometrically anisotropic variograms
thorough revision of function condsim() (new functions
sim.chol.decomp() and sim.circulant.embedding() for
simulating unconditional Gaussian realizations by Cholesky matrix
decomposition and circulant embedding method)
corrected parameter bounds for models RMlgd, RMdampedcos, RMfbm and RMgenfbm
corrected symbol for signal variance in package help page and vignette
complemented value section of various help pages, diverse fixes in order to comply with CRAN policies in Rd-files
substituted dependency on RandomFields, version 3.3.14, by dependency on RandomFieldsMLV3010 version 0.1.0 (= legacy version of RandomFields, version 3.0.10, with reduced functionality)
correction of error in add1.georob, drop1.georob
and step.georob occuring in parallelized computations on
windows OS
forcing socket clusters for parallelized computations in
condsim on non-windows OS
new file inst/NEWS.Rd
new default (FALSE) for argument allow.recursive of
control.pcmp
sanitized help pages complying with KaTeX
only NAMESPACE is imported for the formerly attached packages graphics, parallel, snowfall, stats and utils
vignette and help pages that use suggested packages gstat, lattice and multcomp changed
correction of error in check of initial values of anisotropy
parameters in function georob.fit
