R within a GRASS session works quite well so far. did a fresh svn up of svn://r-forge.r-project.org/svnroot/spgrass and quickly screened pkg\rgrass7\R\initGRASS.R: e.g. Sys.setenv(GRASS_PROJSHARE=paste(Sys.getenv("GISBASE"), "\\proj", sep="")) AFAIK at least the GRASS7.4.x line doesn't use anymore an own copy of the PROJSHARE files; instead it uses the PROJ files itself; that's for all platforms (linux, MacOS, MS Windows, ...). e.g. in OSGeo4W 64bit it's defined as: SET OSGEO4W_ROOT=C:\OSGeo4W64 set GRASS_PROJSHARE=%OSGEO4W_ROOT%\share\proj only in the standalone installer, it's still defined as: set GRASS_PROJSHARE=%GISBASE%\share\proj because it's bundled in the installer. e.g. Sys.setenv(PATH=paste(Sys.getenv("GISBASE"), "\\extrabin;", Sys.getenv("PATH"), sep="")) there is no C:\OSGeo4W64\apps\grass\grass-7.4.1, because all of the dependencies etc are living e.g. in C:\OSGeo4W64\bin, C:\OSGeo4W64\lib, ... I'm not sure about this one: [...] Sys.setenv(GISBASE=gisBase) if (missing(home)) home <- Sys.getenv("USERPROFILE") [...] Sys.setenv(GISRC=paste(Sys.getenv("HOME"), "\\.grassrc7", sep="")) in winGRASS (standalone, OSGeo4W), the rc file lives in C:\Users\YourUserName\AppData\Roaming\GRASS7 and not in %USERPROFILE% and it seems around these lines: [...] Sys.setenv(GISRC="junk") cat("GISDBASE:", getwd(), "\n", file=Sys.getenv("GISRC")) cat("LOCATION_NAME: <UNKNOWN>", "\n", file=Sys.getenv("GISRC"), append=TRUE) cat("MAPSET: <UNKNOWN>", "\n", file=Sys.getenv("GISRC"), append=TRUE) gisrc <- ifelse (use_g.dirseps.exe, system(paste("g.dirseps.exe -g", shQuote(Sys.getenv("GISRC"))), intern=TRUE), Sys.getenv("GISRC")) [...] initGRASS gets in trouble in OSGeo4W. ----- best regards Helmut -- Sent from: http://osgeo-org.1560.x6.nabble.com/Grass-Stats-f4049448.html _______________________________________________ grass-stats mailing list grass-stats@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-stats
