There is a GRASS-R interface available. For documentation, see http://grass.osgeo.org/wiki/R_statistics

Thank Mr. Markus Neteler about your answer, but i have installed spgrass6 in my computer.

I have installed package spgrass6 in R on operating sistem Linux and Windows, but can't use it.

so, what suggestion for me about it?

regard,

Novi Reandy Sasmita

You can try raster or rgdal package. raster will use gdal for reading grass files in read-only. For more information try reading vignette of raster http://cran.r-project.org/web/packages/raster/vignettes/

E.g. for geotiff:

library(raster) # load library

map

".. but can't use it" is a bit too generic to be able to help. What fails? Or the previous comment probably solves it already...

Mr. Markus Neteler, i have installed grass in R, but not running. This display when i run on R

========================

> library(spgrass6)

Loading required package: sp

Loading required package: XML

GRASS GIS interface loaded with GRASS version: (GRASS not running)

> spgrass6()

Error: could not find function "spgrass6"

> loc rian=raster("C:\\Novi Reandy Sasmita\\Citra kecil\\kecil.tif")

Error in .rasterObjectFromFile(x, band = band, objecttype = "RasterLayer", : Cannot create RasterLayer object from this file; perhaps you need to install rgdal first

==========================

and, i installed library(rgdal), but same as before. so maybe you can give me advice

If you get "Error: could not find function "spgrass6"" you need to first install this R extension.
