You did not post to the list - did you subscribe to it properly?
If you need to do this, use Rgui not Rstudio, and GRASS itself, not inside QGIS. Both of these will mess up paths, put things in different places, and make help impossible.

I work with RStudio and have functional knowledge of R.

Try reinstalling the program to fix this problem". Second, I realise that R knows that the location of GRASS which makes me believe that I might not need to use initGRASS after all. initGRASS("C:/Program Files/QGIS 2.14/apps/grass/grass-7.2.0", tempdir())Error in initGRASS("C:/Program Files/QGIS 2.14/apps/grass/grass-7.2.0", : A GRASS location is already in use; to override, set override=TRUE Third, the function gmeta does not work, and here, I am at a loss to know why. gmeta(ignore.stderr = FALSE)Error in if (get("SYS", envir = .GRASS_CACHE) == "WinNat" && nchar(WN_bat) == : missing value where TRUE/FALSE needed Can you help me with having the right set up to use rgrass7 ?
