[R-sig-Geo] zero out the dataframe?

[Philip A. Viton]

Given a Spatial*DataFrame, is there some easy way to delete the
dataframe objects, leaving only the Spatial* part? (I have a
very large spatial dataframe, and I want to do come calculations that
don't involve the data part; and I hope that this could
speed things up). I tried setting the data slot to NULL, but
apparently this isn't allowed.

Thanks!
