[R] bug in readRAST6 function in package spgrass6

[Rainer M Krug]

Hi

if I try to import a raster layer which consists only of NULL values
from grass by using the  readRAST6, I get an error message:


> readRAST6("HSericea_seedsDisperse_2007")
ERROR: Invalid value for null (integers only)
Error in readBinGrid(rtmpfl11, colname = vname[i], proj4string = p4,
integer = to_int) :
  no such file:
/home/rkrug/Documents/Projects/AlienSpread/R/../grass/simulation/.tmp/ecolmod/HSericea_seedsDisperse_2007


Thanks

Rainer
