Please always try to provide a reproducible example using a standard data 
set. In addition, the output of traceback() following the error would 
be helpful. Are you running R inside GRASS, or using R to initiate GRASS?

Consider using the grass-stats list:

https://lists.osgeo.org/mailman/listinfo/grass-stats

as it is more likely to yield results, but there also provide an example 
that anyone can reproduce. The example should avoid loading other 
packages, and should be run from the R console (not, say, RStudio).
