Error with r.mask through rgrass7

Hello all,

I've got R 3.2.4, GRASS GIS 7.1.svn, and rgrass7 installed.

I've started my GRASS session from R with:

initGRASS(gisBase = "C:/Program Files/GRASS GIS 7.1.svn", home = tempdir(),
override = TRUE)

Then I tried to use r.mask from R and I got the following error:

Error in system(cmd0, intern = TRUE) : 'r.mask.exe' not found
Error in parseGRASS(cmd, legacyExec = legacyExec) : r.mask not found

Anyone can help with this?

Thanks.
