Hi Vero;I will try that as well. I just need an indication that grass is running before I execute my script. I think that this may work if I put it at the very beginning.

what about gmeta()? If grass is running, it gives you location and region metadata, otherwise it rises an error... 

Or you could also ask in the grass-stats list: https://lists.osgeo.org/mailman/listinfo/grass-stats

Hi;I usually start GRASS from my RConsole as so:
#perform initial GRASS setupinitGRASS("C:\\OSGeo4W64\\apps\\grass\\grass-7.4.1", home = getwd(), gisDbase = "GRASS_TEMP", mapset = "PERMANENT", override = TRUE)
and I never had problems until last week. I was getting errors and couldn't figure out why. Later on I came to find out that my GRASS instance was closed.I don't know why GRASS unexpectedly close without notification. With that said, is there a way in R to check if GRASS is still running in the background?I can probably manually check my task manager to see if there is a process running but in a more elegant way I want to do it from R.
