[R] export variable from bash to R

Hi Barry

Thank you very much for your reply. I changed my scripts according to your
suggestions - this is how they look now:


VARIABLES=( a b c d )

for i in ${VARIABLES[@]}; do
      export VARIABLENAME=$i
      Rscript -e 'source("myscript.R")'

and in the R program, I used
args <- Sys.getenv("VARIABLENAME")  instead of args <- commandArgs(TRUE)

But when I add the "R --slave", the program hangs, so I left it out (you
said it was just to cut out the startup messages, so I assumed it shouldn't
really matter). It's still not working, though. There is no error message,
but the R program still doesn't seem to be executed (@Krzysztof: The R
program makes plots - since these plots are not produced,  I figured that
something with the call of myscript.R is not working)

Any ideas or suggestions?
