[R-sig-Geo] polygons to grid?

[Agustin Lobo]

Hi?

Is it possible to perform a vector to raster conversion in R,
from SpatialPolygonsDataFrame to a SpatialGrid (providing the final resolution?

In particular, is it possible to do it using package raster?

(I know this can be done using gdal or grass etc, but I'm trying
to find an "only R" solution)

Thanks

Agus
