Hi all,

I am attempting to do SDM in R, mostly I have used the 'dismo' package.  My
problem is that all the methods call for a raster stack as the input
representing the environmental layers.  However, my processing steps leave
me with a table of extracted values for each occurrence (much like section
4.2 in the dismo vignette).  I am wondering if there is a way to feed this
type of data into these modeling methods, in dismo or any other SDM
package.

Thanks!
