[R-sig-Geo] convert from spatstat to sp

[Robert J. Hijmans]

Peter,

If this is an "im" object you can use

library(raster)
r <- raster(im)
r <- polygonsToRaster(pols, r, mask=TRUE)

You can also use the coercion methods between spatsat and sp that are
available in maptools and then use sp overlay methods

I do not know if you can clip in spatstat, but I would guess so.

Robert
