<div>Or is it easier using Python?<div><div></div><div class="h5"><br><br><div class="gmail_quote">On Fri, Apr 16, 2010 at 3:28 PM, Markus Neteler <span dir="ltr"><<a href="mailto:neteler@osgeo.org" target="_blank">neteler@osgeo.org</a>></span> wrote:<br>

</div></div>Yes. Example:<br>
<br>
GRASS 6.4.0svn (nc_spm_08):~ > cat R_batch_nc.R<br>
library(spgrass6)<br>
mydem <- readRAST6("elevation")<br>
summary(mydem)<br>
<br>
To run it inside GRASS, do<br>
<br>
GRASS 6.4.0svn (nc_spm_08):~ > R CMD BATCH R_batch_nc.R<br>
<br>
The standard output result is stored in R_batch_nc.Rout. Of course<br>
you can also generate new GIS data in R and write them back to<br>
GRASS with writeRAST6() or writeVECT6().<br>
<br>
Hope this helps,<br>

PS: Yes, I am also suprised that the GRASS Wiki isn't full of<br>
useful scripts calling R in GRASS in batch mode...<br>
