António,
You must run this from the GRASS term window; first start R at the GRASS
shell prompt, by typing R; then load spgrass6: library(spgrass6) — the
supporting libraries (sp, rgdal, etc.) must be installed in R first.
Regards,
Tom

Hi,
I've installed spgrass6, which apparently went fine (on my mac).
All the examples I found run R commands from the GRASS console (hence
not being necessary to specify the GRASS LOCATION, etc.
Isn't it possible to specify a GRASS LOCATION from within the R
interface?
In R, I loaded spgrass6, then tried:
> initGRASS("/Applications/grass-6.4.app")
and I get:
/bin/sh: g.gisenv: command not found
/bin/sh: g.gisenv: command not found

If I want to start GRASS and open a specific mapset, would this work?
initGRASS("/Applications/grass-6.4.app",
GISdbase="/Users/antonio/Documents/grass", location="pt_etrs89",
mapset="interior")
(well, it doesn't, I'm just not sure why...)
Thank you
