[R-sig-Geo] Convert from spatialpointsdataframe to spatialpoints

[Robert J. Hijmans]

Manuel.

Did you try it without converting? The help file in raster says it
needs a SpatialPoints* object. The '*' is a wild card that in this
case stands for 'DataFrame'.

The answer to your question:

as(x, 'SpatialPoints')

You could find the answer to many of this type of questions by reading
the vignettes of sp and raster, and by searching the R-sig-geo help
archives, and looking at the R spatial wiki.
