Re: [GRASS-stats] Error when starting grass from R (grass installed thru osgeo4w)
Hi again,
So, I tested as suggested:
1. Open R console within OSGeo4W Shell,
2. library(rgrass7)
3. initGRASS(gisBase = 'C:/OSGeo4W64/apps/grass/grass-7.4.0', gisDbase =
'C:/Users/RETA/Documents/grassdata', location = 'nc_spm_08_grass7', mapset
= 'user1', SG='elevation')
and I now get:
unused argument (gisDbase = 'C:/Users/RETA/Documents/grassdata')
anything else to test/set?
best,
Vero

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: ", "\n", file=Sys.getenv("GISRC"),
append=TRUE)
cat("MAPSET: ", "\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.

Re: [GRASS-stats] Error when starting grass from R (grass installed thru osgeo4w)
Sorry, no idea. Testing was from R for Windows using initGRASS(), but a long
time ago. Starting R from within GRASS, picking up the environment variables
already created during GRASS startup msy be less fragile, as you are using an
existing location.

it's a missing dll.
Are you invoking R from inside the OSGeo4W command console?

Re: [GRASS-stats] Error when starting grass from R (grass installed thru osgeo4w)
OK, thanks for confirming that OSGeo4W remains feasible for rgrass7; I don't
have access. Does usability include initGRASS()? This would be most fragile
because environment variables are being set, and condition on Windows and
OSGeo4W.
