Hi Barry
Thank you very much for your reply. I changed my scripts according to your
suggestions - this is how they look now:
#!/bin/bash
VARIABLES=( a b c d )
for i in ${VARIABLES[@]}; do
export VARIABLENAME=$i
Rscript -e 'source("myscript.R")'
done
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 didn't hang, it was probably sitting there waiting for you to say q() - I was just using it interactively.
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?
Does it produce any printed output? Can you add some print statements
to see where it gets to?
$ cat myscript.R
print("Hello world")
$ Rscript -e 'source("myscript.R")'
[1] "Hello world"
- here at least I know its finding the right script.
