other users of Windows (I am not a Windows user) please report whether this

to resolve this.
tested here on a win 10 64-bit box, and osgeo4w-winGRASS7.0.5; following
steps for testing:
- start a osgeo4w-winGRASS7.0.5-session
- adding R to %PATH%:
C:\>set PATH=%PATH%;"C:\Program Files\R\R-3.3.1\bin"
C:\>echo %PATH%
C:\OSGEO4~1\apps\grass\grass-7.0.5\lib;C:\OSGEO4~1\apps\grass\grass-7.0.5\bin;C:\Users\hkmyr\AppData\Roaming\GRASS7\addons\bin;C:\OSGEO4~1\apps\Python27\Scripts;C:\OSGEO4~1\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\WBem;C:\OSGEO4~1\apps\msys\bin;"C:\Program
Files\R\R-3.3.1\bin"
- following library versions are installed:
install.packages("sp") # sp_1.2-3
install.packages("rgdal") # rgdal_1.1-10
install.packages("rgrass7") # rgrass7_0.1-8
- then typing R in the osgeo4w-windows console:
C:\>R

- and loading rgrass7:

Lade n├Âtiges Paket: sp
Lade n├Âtiges Paket: XML
GRASS GIS interface loaded with GRASS version: GRASS 7.0.5 (2016)
and location: nc_spm_08_grass7
beside some locale setting issues, library("rgrass7") works here on my
side.
I've tested it on a few 32bit/64bit win7/win8/win10-boxes, no issues so far
here in testing on my side.
taken from the mentioned error report:
> Error : .onAttach in attachNamespace() f├╝r 'rgrass7' fehlgeschlagen,
> Details:
> Aufruf: if (class(t0) != "try-error" && is.character(t0) && nchar(t0) >
> Fehler: Fehlender Wert, wo TRUE/FALSE n├Âtig ist
what can be the reason of such an attachNamespace() issue?
two installed rgrass7 packages (with and without admin rights)?
locale issue?
path issue?
anything else to test?
