[R-sig-Geo] Problem with initGRASS

[Chris Reudenbach]

Jaime,

if the location of your GRASS installation is not known you may also 
give the link2GI package a try.

try link2GI::linkGRASS7() for a "brute force" searching and linking. 
This should setup your enviroment for using the newest GRASS version.

cheers Chris
