Hi, you can run R in a grass terminal, and load data via spgrass6 package, readRAST6 or readVECT6. Or export raster and read with rgdal. Hope it helps. Leonardo Hardtke On 07/27/2010 01:30 PM, Etienne DELAY (deust 2010) wrote: I'm come back :-) I want to try clustTool in GRASS, so I reset

Hi! I never used clustTool before. I made a try and i think I found the trick :-). You have to transform your (SpatialPointDataFrame) data to a dataframe... Vine1.df=as.data.frame(Vine1) and then you can Set acctive data in the GUI! hope it helps! Leonardo On 07/27/2010 09:06 PM, Etienne
