[R-sig-Geo] Extract raster attributes ( factors) directly for points

[Jonathan Greenberg]

Nevil:

I think if you:

extract(...,sp=TRUE) you'll get what you are looking for (that will
extract the values and place them into the data frame of the spatial
object -- you can always peel off the data.frame afterwards using e.g.
as.data.frame).
