[R-sig-Geo] Problem with rgdal

[Michael Sumner]

I suspect that your rlm1ext is not spTransform-able.

library(rgdal)
spTransform(1, CRS("+init=epsg:4326"))
Error in spTransform(1, CRS("+init=epsg:4326")) :
  load package rgdal for spTransform methods

It might be hard to test that there couldn't ever be a method for
spTransform for some given input, but this does seem a little too
open-ended.

Cheers, Mike.
