[GRASS-stats] R (spgrass6) / GRASS r.in.gdal error

[Alexandre Villers]

Sorry for double posting if it did
-------------------------------------------------------------------

Good afternoon,

While trying to import a GTiff and process it with spgrass6 with the 
following:

execGRASS("r.in.gdal", flags=c("o","overwrite"), 
parameters=list(input="E:/Boulot/WildlifeTrianglesFinland/Covariates/Rainfall/Rain.year1989.tif", 
output="ref", _band=1_))

or

execGRASS("r.in.gdal", flags=c("o","overwrite"), 
parameters=list(input="E:/Boulot/WildlifeTrianglesFinland/Covariates/Rainfall/Rain.year1989.tif", 
output="ref",_band="1"_))

I get


Error in doGRASS(cmd, flags = flags, parameters = parameters) :
   Parameter<band>  does not have integer value



When I do not specify the band value, the two bands of this GTiff are 
imported properly....
Any idea ?


Alex

P.S.:
