gstat 2.1-2 (2024-09-05)

• variogram() supports stars (raster) objects, benefiting from them being gridded

gstat 2.1-1 (2023-04-06)

gstat 2.1-0 (2022-10-19)

• import sftime; modify krigeST() variogram functions to accept sftime objects for data (as alternative to STI or STIDF), and stars or sftime objects for newdata; #108 with great help from @henningte

• fix Gaussian cosimulation, probably introduced in 2016, #106

gstat 2.0-7 (2021-03-19)

• return NA as estimate when prediction/simulation fails; #80

gstat 2.0-6 (2020-05-18)

• fixes object 'ret' not found bug introduced by #63; #65 #66 #70

gstat 2.0-5 (2020-04-04)

• use multiple cores in variogramST, using pkg future; #63 by @sigmafelix

• fix bug with conditional simulation using stars target grid and nsim=1, #58

gstat 2.0-4 (2020-01-21)

• fix CRAN warning issue

gstat 2.0-3 (2019-09-26)

• fix bug in support for sf objects; #46

• fix krigeTg for the case when data or newdata are of class sf or sfc; #51

gstat 2.0-1 (2019-04-25)

• try to fix CRS issue found on OSX

• check for temporal unit in krigeST opposed to covariance function and assign the temporal unit found in krigeST to the spatio-temporal variogram for consistency in case none has been provided by the model; add warning when ST variogram doesn't have a temporal unit attribute; #42

gstat 2.0-0 (2019-02-28)

• add plot.variogramModel; #40

• support sf and stars objects, for vector and raster data, respectively; #39

gstat 1.1-6 (2018-04-02)

• address warnings from Tomas Kalibera's static code checking

gstat 1.1-5 (2017-03-12)

• fix auto-choosing of variogram parameters if only variogram model type is given, https://github.com/edzer/gstat/issues/17

gstat 1.1-4 (2017-01-11)

• Fix #17
  • Fix #14
  • Fix #12
  • Fix great circle distance bug; see https://stat.ethz.ch/pipermail/r-sig-geo/2016-December/025251.html

• fixed memcpy for overlapping regions error, found in valgrind checks by Brian Ripley
• fixed a few more (small) memory leaks

gstat 1.1-1 (2016-02-21)

• Further cleaned up C source code, got rid of lex and yacc files
• Improve fit.variogram to choose initial values for range, sill and nugget before fitting, and fit over a range of model types
• allow NA values in vgm
• Fixed #1

gstat 1.1-0 (2015-10-18)

• remove meschach matrix library, rewrote interface, link to R's lapack
• improve notification in case of singular matrices
• remove all C code that was not used by R package gstat
• add Makevars, remove configure
• remove links to ai-geostats.org
• wrap fit.StVariogram example in dontrun
