Dear list members,


I am trying to create a raster from points, but I read the points from a 
shapfile, so I have the points object as a SpatialPointsDataFrame.
To use the function pointsToRaster I need the points as SpatialPoints.

How to convert a SpatialPointsDataFrame object to a SpatialPoints?
Best,

Manuel
