Hi, again.

Following Markus Neteler's excelent R GRASS tutorial I've been able to
import some GRASS (vector) point data into R and I've been able to
interpolate the data. Now I'd like to be able to get the data back into
grass to be able to make a nice map of the interpolated data. But I
can't seem to find any advise on how to do it. Is it even possible?

I have an object ws.tmean_tr1 which is

>> str(ws.tmean_tr1)

List of 3
 $ x: num [1:132] 2866517 2874825 2883133 2891441 2899749 ...
 $ y: num [1:132] 6538650 6548635 6558619 6568604 6578589 ...
 $ z: num [1:132, 1:132] -6.52 -6.57 -6.63 -6.68 -6.73 ...

x is the E-W coordinate, y is the N-S cordinate and z is the
interpolated temperature. How can I make this into a GRASS raster
map?

The only other reference I found was this:
http://grass.itc.it/pipermail/statsgrass/2005-August/000287.html, but
I'm not able to parse that info into my case. Please help!
