[R-sig-Geo] Problem in reading .grd file using raster package

[Tim Appelhans]

Soumen,
ratser uses .grd (+.gri) file endings for it's own file format. That has 
nothing to do with Geosoft .grd files, apart from the fact that the file 
endings are identical. My guess is if gdal is not able to read it, you 
will still need to convert it somehow before getting it into R.
