have access. Does usability >include initGRASS()? This would be most fragile<br>

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