Data Analysis with R statistical data analysis language provides:

R-stats is an ideal extension for GRASS. R is described in greater detail here: What are R and CRAN. You can freely download the R software (MS-Windows/Linux/MacOSX/etc binaries are provided). A general web portal related to geostatistics is found at AI-GEOSTATS.
