R help - Jun 2013 - passing of arguments to R CMD BATCH in bash script that is submitted to torque (Linux platform)

Dear all

I want to call R repeatedly in batch mode from a bash script that is then
submitted to torque.

My calls to R depend on optional arguments.

When I introduce these arguments as literals, the calls work fine, for instance:

R CMD BATCH  --no-save "--args PERIOD='08' YEAR='2008'
SC='BAU' " preparecostvectors.R

However, the arguments PERIOD, YEAR and SC are really variables over which I
'loop'.

When these variables are defined in the same script as the call to R CMD BATCH,
this still works, for instance:

year="2008"
sc="BAU"
R CMD BATCH  --no-save "--args PERIOD='08' YEAR=\"$year\"
SC=\"$sc\"  " preparecostvectors.R

Things go wrong when the script is called from another script, for instanced
with:

qsub -v year="2008",sc="BAU"  ATLAS_assign.sh

"echo $sc" and "echo $year" in ATLAS_assign.sh yield
"BAU" and "2008" respectively.

Thus, as far as I can see, nothing goes wrong in the passing of the optional
arguments in qsub.

However,

R CMD BATCH  --no-save "--args PERIOD='08' YEAR=\"$year\"
SC=\"$sc\"  " preparecostvectors.R

is not executed. I do not get even an Rout file, so I suppose the R script is
not even called.

I suppose there is something wrong in the format in which I submit year and sc,
but I do not see what.
