You need to provide a lot more information, including the messages displayed when spgrass6 (and possibly rdgal) are loaded, and the output of sessionInfo(). These will tell us which versions you are using. Then also run:
execGRASS("g.list", parameters=list(type="vect")) to check that the vector object you think that you have is actually visible. It may be in a mapset that is not on your search path.
