] convert from spatstat to sp
Hello all,
Is there any way to convert from spatstat to sp?
Specifically, I am looking to clip a density plot produced in spatstat
to include only points within a polygon boundary in a shapefile. if
there is a way to clip in spatstat, this would also be acceptable

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
There is; if your question is about converting an object of class im
(spatstat) to an object of class SpatialGridDataFrame (sp), it is in
package maptools:
library(spatstat)
whitenoise - im(matrix(rnorm(1200),30,40))
library(maptools)
x = as(as(whitenoise, SpatialGridDataFrame),
