I suppose you mean library(GRASS), what you have to use when R shall run 
inside GRASS. 

My problem is not the interface with R, that works fine so far but the chart 
option in GRASS 5.0.2.

I could in R do rast.get() for my rastermaps and display them in R and the 
barchart wouldn't be a problem but R slows down significantly when trying to 
handle a data frame of a few 100 000 values, therefore I would like to keep 
the whole rastermap in GRASS and only transfer the values for the barchart 
into GRASS and display the charts there. 

Or I upgrade to 5.1. but as long as it is not meant for productiv use, I 
prefer to keep 5.0.x. 

cheers, Martin
