I assume you use Linux.

The easiest way of using R and GRASS GIS together, is starting GRASS GIS
and then in starting R in GRASS. This way, initGRASS() is not needed
anymore as the environment is already set up.

Are you sure that you gisBase is correct? Does GRASS work if you start
it?

Cheers,

Rainer
