When asking a question about R software, please always include the output 
of sessionInfo(), which shows what versions you are using on what 
platform.

In this case, on standard R Windows 2.12.0, install.packages("spgrass6") 
should pick up spgrass6, sp, and rgdal from your chosen CRAN mirror, and 
XML from CRAN extras:

http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.12/

which is the second of the enabled repositories on standard Windows 
installs. If this doesn't work for any reason, install sp, rgdal, then 
download and install XML from the address above, finally installing 
spgrass6.

There is also a statsgrass mailing list for interface questions:
