library(raster); use with function: writeRaster("raster object", "name",
format="ascii"); format="raster" for *.grd files
library(rgdal); use with function: writeGDAL("rgdal object",
fname="name", drivername="AAIGrid"); use gdalDrivers() to identify your
preferred drivername for *.grd
you certainly have to change your grid object to a raster object when
using raster package.
All the best!
