I am using
rgrass7 with R and by typing the following
initGRASS(gisBase = "C:/GRASS/GRASS_GIS_7_3_svn", home=tempdir(), gisDbase = "C:/Users/main/Desktop/data", location = "Thesis",mapset = "user", override = T)
I get this error
Error in if (get("SYS", envir = .GRASS_CACHE) == "WinNat" && nchar(WN_bat) == : missing value where TRUE/FALSE needed
Now I was wandering if anyone else had the same problem at some point and knows how to prevent it.
