[R-sig-Geo] LL to UTM

You *may* be able to accomplish this using R easily (I'm sure it's 
doable), but I'm do not know how to do the conversion. I would suggest 
as an alternative to do your work using GRASS GIS 
(http://grass.itc.it/). R interfaces very well with GRASS and making 
your LL to UTM conversion (and back) would be trivial using GRASS. You 
can also use R within a GRASS session interactively or 
non-interactively, embedded within a script.

I hope this is helpful to you.
