Right- well I did as you suggested and seem to have fixed the problem.

The problem appeared to be that some carriage returns were not 
registering in the Mac Os X R editor. So even though it looked like it 
was on a new line, it wasn't. It wasn't a line wrap issue, these were 
actually returns that I had hit that just weren't registering. I had one 
chunk of code which showed what I thought was the problem when R 
crashed. When I opened up the script again after restarting, the problem 
disappeared, so somehow the returns started to be seen.

thanks for your help.
