GRASS GIS interface loaded with GRASS version: (GRASS not running)

from the https://cran.r-project.org/web/packages/rgrass7/rgrass7.pdf

Examples
## Not run:
initGRASS("/usr/bin/grass-7.0.0", home=tempdir())
initGRASS("C:/GRASS", home=tempdir())
## End(Not run)

as an used windows user I've tried first with Windows-typical backslash ;-)

initGRASS("C:\\Program Files\\GRASS GIS 7.1.svn", home=tempdir(),
gisDbase="C:\\grassdata", location="nc_spm_08", mapset="user1")

> initGRASS("C:\Program Files\GRASS GIS 7.1.svn", home=tempdir(),
> location="C:\grassdata\nc_spm_08\", mapset="user1")
Fehler: '\P' ist eine unbekannte Escape-Sequenz in der Zeichenkette
beginnend mit ""C:\P"
error: '\P' is an unkown escape sequence beginning with with ""C:\P"

then I tried double backslash

initGRASS("C:\\Program Files\\GRASS GIS 7.1.svn", home=tempdir(),
gisDbase="C:\\grassdata", location="nc_spm_08", mapset="user1")

> initGRASS("C:\\Program Files\\GRASS GIS 7.1.svn", home=tempdir(),
> gisDbase="C:\\grassdata", location="nc_spm_08", mapset="user1")
gisdbase    C:/grassdata 
location    nc_spm_08 
mapset      user1 
rows        6 
columns     8 
north       222800 
south       222740 
west        642590 
east        642670 
nsres       10 
ewres       10 
projection  +proj=lcc +lat_1=36.16666666666666 +lat_2=34.33333333333334
+lat_0=33.75 +lon_0=-79 +x_0=609601.22 +y_0=0 +no_defs +a=6378137
+rf=298.257222101
+towgs84=0.000,0.000,0.000 +to_meter=1 

and the slash mentioned in the manual example

initGRASS("C:/Program Files/GRASS GIS 7.1.svn", home=tempdir(),
gisDbase="C:/grassdata", location="nc_spm_08", mapset="user1")

> initGRASS("C:/Program Files/GRASS GIS 7.1.svn", home=tempdir(),
> gisDbase="C:/grassdata", location="nc_spm_08", mapset="user1")
gisdbase    C:/grassdata 
location    nc_spm_08 
mapset      user1 
rows        6 
columns     8 
north       222800 
south       222740 
west        642590 
east        642670 
nsres       10 
ewres       10 
projection  +proj=lcc +lat_1=36.16666666666666 +lat_2=34.33333333333334
+lat_0=33.75 +lon_0=-79 +x_0=609601.22 +y_0=0 +no_defs +a=6378137
+rf=298.257222101
+towgs84=0.000,0.000,0.000 +to_meter=1 

not sure what R's normal notation of MS windows paths are (slash or double
backslash), maybe an addition to the manual would be worth?

will testing winGRASS modules and addons later.
