Thanks, corrected. This was because the instructions on this list were 
interim, the correct ones are those in GRASS-News:

rS <- "http://r-spatial.sourceforge.net/R"
install.packages("spgrass6", repos=rS)

rather than the deprecated source branch (which is where you were looking 
- will be removed before long).

Thanks for reporting this,

Best wishes,

Roger
