Thanks Roger. i had been reading some data information in regards to the rgdal 
package, and thought I would put out a question as soon as possible. Thanks 
for all of the hard work!

PS: I asked this question as I am currently leading a seminar on open source 
software tools for soil scientists, and wanted to highlight the GRASS-R 
coupling. Since many of the students are using macs, I wanted to make sure 
that I would be able to give them an example that they could implement 
themselves. 

Cheers,
