[R-pkg-devel] R CMD BATCH plot output

[Josiah Parry]

Thanks, Duncan!

Is there a way to override this using the command line arguments?

I'd like to be able to have a generalizable way to address this without
having to modify R source code.

My understanding is that when there is a plot output, R CMD BATCH uses the
PDF device which is a fair default.

However, there is not any use of `dev.new()` or `pdf()` called anywhere in
the code.
