strength of r.mapcalc, they can say system("bash") and do it from the<br> shell, returning to R by closing the shell. The history file for the<br> under-shell will not, however, be recorded (at least not in the same<br>
place).</blockquote><div><br>I actually managed to get r.mapcalc working quite nicely without any hassles so far. I agree that this could be excluded from the do_GRASS() or at least get internally a special treatment (r.mapcalc was actually one reason why I used GRASS from R as it was much easier then using internal R mechanisms for that.)<br>
