[R] Fwd: Converting Lat Lon data in coordinates in R

The sp package has what you need.
spTransform() will convert from lat/lon to other coordinate systems.
char2dms() will convert lat/lon coordinates formatted as you have them
into numeric lat/lon values. You may wish to use
as.numeric( char2dms( [your data] ) )
It will take some effort to get your data structured so that spTransform()
will work with I.
And I suggest asking further questions on r-sig-geo.
