Hi Arnold
If i remember right, its in the Rgdal package. You need the librariy gdal in
your system, this gave me some problems on Ubuntu Linux. Then what you are
looking for is something like :
points <- spTransform(points, CRS = ("+proj=longlat")
remember that you have to give the right proj4string to your
spatialDataPoints before.
Hope this is right, but otherwise i will be corrected i am sure ;)
Regards
Jan
