converting from UTM to Decimal degrees
See functions ?project and ?spTransform in the rgdal package. The former is simpler but is only for transforming a matrix of coordinates from or to longitude / latitude, and no datum transformation is possible. The latter can transform Spatial* objects arbitrarily from or or to any PROJ.4 coordinate system and includes datum transformations.

Dear R Sig Geo People: Is there a function to convert UTM coordinates to Decimal degrees, please? ?This is just for a few points; nothing big. I know that this is a relatively easy one, but thought I'd check before I wrote up something. Thanks, Erin Erin M.
