<p class="MsoNormal"><span lang="EN-US">Using GRASS 7.0.3 on Ubuntu Linux,<br>
<br>
I'm attempting to recreate the example of r.stream.distance shown at<br>
</span><a href="https://grass.osgeo.org/grass70/manuals/addons/r.stream.distance.html" target="_blank"><span lang="EN-US">https://grass.osgeo.org/grass70/manuals/addons/r.stream.distance.html</span></a><span lang="EN-US"><br>
<br>
by passing these comands to GRASS from within an R session. I can't figure out the correct syntax to pass this command to the system and also GRASS, any suggestions ?<br>
<br>
The original code for GRASS command line in the example is<br>
<br>
# Create outlet<br>
echo "636645,218835" | v.in.ascii -n input=- output=outlet separator=","<br>
<br>
<br>
I've tried lots of combinations of both system() and execGRASS() including this<br>
<br>
system(message ("327500.00,523896.55") | "v.in.ascii", input="-", output="outlet", separator=",", flags=c("n", "overwrite"))<br>
<br>
<br>
<br>
<br>
but have been unsuccessful.<br>
<br>
Any suggestions?<br>
<br>
Thanks, J<span style="color:#888888"><br>
