Hi!
I never used clustTool before.
I made a try and i think I found the trick :-).

Vine1.df=as.data.frame(Vine1)
and then you can Set acctive data in the GUI!
hope it helps!

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.
