Hello: I am a new R user trying to integrate existing tcl/tk code into R. I installed R on a linux system and was able to access the tcl interpreter that came with R just fine. However I am unable to access some tcl packages with the tcl package require command. Is it possible for R to use the tcl interpreter that already exists on the system in place the one that (apparently) came with R? Thanks, Kevin Kevin Werner Hydrologist, NWS/CBRFC
