After forking, as of now:

install.packages("spgrass", repos="http://R-Forge.R-project.org")

installs the "new" package for GRASS 7. Function names are now without the 
trailing 6 to avoid confusion, and all examples run correctly in Spearfish 
in GRASS 7.0 RC1.

Could someone please run the examples in Spearfish in GRASS 7.0 RC1 on 
Windows after installing the Windoes spgrass binary (R 3.1) from R-Forge, 
and report back?

Could someone please install spgrass from source on OSX (pre-Yosemite and 
Yosemite), run the examples in Spearfish, and report back?

The existing spgrass6 does not work with GRASS 7 following recent changes 
in GRASS parameter names - it may be modified either to permit these, or 
to remove GRASS 7 conditions, leaving it just for GRASS 6.

Best wishes,

Roger
