I am running in Windows 8. I noticed this particular problem running a script
in R 2.9.2 from the command line.
I have an r script that I wrote some time ago. It is fairly complicated and
does a lot of time-consuming optimizations, following which it populates a SQL
database with the results. The whole thing takes maybe 10-15 minutes to run.
Because it takes a while to run, I have it automatically kicking off in the
early morning using a command-line instruction from System Scheduler.
The script ran fine for a long time...actually, for a few years. Recently, it
started to run but kill out at one point. When I run it from a new R session,
manually pasting in the script, it runs fine.
After some elementary debugging I discovered that the error is happening when I
call dev.new() . Again, this never had a problem before, and it doesn't have a
problem when run in the R window, but when the script is run in the command
line it throws this error:
"no suitable unused file name for pdf()"
No idea what this means as I'm not calling a pdf device...unless somehow when
it's command-line R assumes you don't want a window but a pdf. If that's the
case I still can't figure out why there's suddenly a problem finding "unused
file names."
Any suggestions would be welcome!
Thanks,
Mike
