I am looking for a way to reproject data that exists in a
SpatialPolygonsDataFrame. (I think it's the same data as in the rworldmap
package.)

I am quite familiar with mapproject() which works well the maps and mapdata
packages and am hoping there is an equivalent to mapproject() that could
work with SpatialPolygons data.

Or is there a simple way to get the x an y data arrays out of the
SpatialPolygons?

Thanks in advance,

Jon
