First problem, unkown OS. Guess Windows (CP1252??) from the odd characters 
in your email, unkown version. Unknown R version and unkown rgrass7 
version. No other reports of issues that are known. Are you using OSGeo4W 
GRASS or native GRASS? That shouldn't matter, rgrass7 will load with no 
GRASS present.
