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.
