Goord morning,<br>
<br>
I would like to use v.mkgrid (with spgrass6) and I need to specify box
and grid parameters, which both require 2 values box=5000,5000
grid=1000,1000<br>
How do I specify this in my parameters list ?<br>
parseGRASS6("v.mkgrid") returns<br>

execGRASS("v.mkgrid", flags="overwrite",
parameters=list(map="grilleTest",
grid=c(as.integer(100),as.integer(100)), box=c(5000, 5000),
position="region"))<br>
returns<br>
<i>Erreur dans doGRASS(cmd, flags = flags, parameters = parameters) : <br>

not get it....<br>

Thanks<br>
