Hi Max,

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!
