Fwd: [GRASS-user] Spgrass6 and R using GRASS Bash Scripts
Greetings Thanks Markus and Milton for your help But... Imagine that I'm running a GRASS Script with Module, and all GRASS functions. How can I integrate it in there? I mean, the user selects a raster and How can i use that input to run a Script that calls R? That is my question. Because I can have a script, like you sent me, but it's not interactive... Or is it easier using Python?

Example: GRASS 6.4.0svn (nc_spm_08):~ cat R_batch_nc.R library(spgrass6) mydem - readRAST6(elevation) summary(mydem) To run it inside GRASS, do GRASS 6.4.0svn (nc_spm_08):~ R CMD BATCH R_batch_nc.R The standard output result is stored in R_batch_nc.Rout. Of course you can also generate new GIS data in R and write them back to GRASS with writeRAST6() or writeVECT6(). Hope this helps, Markus PS: Yes, I am also suprised that the GRASS Wiki isn't full of useful scripts calling R in GRASS in batch mode... ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] Spgrass6 and R using GRASS Bash Scripts
Good Morning I need to do something similar to what Neteler/Mitasova do in their book with spgrass6 and R. Since I will have to perform this a couple of times I want to build a simple Script with input/output GUI. But I have never seen a GRASS Bash script that calls R and spgrass6. So my question is?

Re: [GRASS-user] Spgrass6 and R using GRASS Bash Scripts
Hi Gilbert, There ist more than one way. I will tell you the way that works for me: 0. Be sure your Rgui.exe are in the windows path like C:\Program Files (x86)\R\R-2.9.0\bin 1. Start grass/MSYS (sorry, I am on windows). 2. Connect to you mapseet 3. inside MSYS shell type: Rgui.exe 4. Inside R you can run your scripts like: #this is on R require(spgrass6) gmeta6() myMap=readRAST6(...) summary(myMap) system(g.list.exe rast) -- But I know that the way I do are not updated :-) cheers milton 2010/4/16 Gilbert Ferrara gilbertferrara1...@gmail.com Good Morning I need to do something similar to what Neteler/Mitasova do in their book with spgrass6 and R.
