Downloading sp and related projects

• The sp package itself should be obtained from CRAN (by using install.packages(), or throught the menu: install packages from CRAN); this is the preferred way, but if you need as yet unreleased functionality, try the CVS tree and pre-releases which may be made available for testing on the project download page
• from the R contributed repository at this site which was used for packages not yet released to CRAN. All of the content in this repository is now available on CRAN, and it is only maintained as an archive for users of older versions of R pre-dating release on CRAN. It is also possible to install online within R, for instance:

  rSpatial <- "http://r-spatial.sourceforge.net/R"
  install.packages("spgrass6", repos=rSpatial)
  

  Windows binaries will be made available using this channel, and older versions will be available as sourceforge file releases.
• using CVS tree, by using anonymous cvs, e.g. by:

  cvs -d:pserver:anonymous@r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial login
  cvs -z3 -d:pserver:anonymous@r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial co -P sp
  

  where you can give a return on the passwd prompt. See this linl for further details. For other modules, replace sp with e.g. spgrass6. Click here and follow CVS -- Browse the CVS Tree to satisfy your curiosity about what else is there.
