R help - Jun 2006 - arima fails when called from command line

I'm sure there is no consistent way to reproduce this, but I'm hoping
someone has some information.

I have a time series we'll call y.  The data gets updated every day, so
I run a cron job that fits and predicts from an arima(0,0,1) X (1,1,1)_7
model.

When I open R and run the script, it processes completely.  If I call
the script via a crontab entry

R --no-save --slave < myscript.R

then the fitting of the arima model fails.  I have checked to make sure
the shell is calling the correct version of R, so it should be no
different than when I am using it interactively ...right?

Thanks for your time on this,
B

hi : i had a similar problem a few weeks agowhen i was tryin g to use R CMD
BATCH ( but when i sourced the copde at the r prompt everything worked fine ).
eventually, i fiigured out that it had to do with a read.tale statement having a
col.names argument that was too long for the script to handle. if it doesn't
read in the data correctly,
this might be causing the arima failed message. that's
just a guess though. someone else may have a better idea.
