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

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.

Hey folks! I am working with R CMD BATCH and providing a providing a
logfile output e.g.

R CMD BATCH main.R 2024-07-28.log

This creates the desired log file with the contents of stdout and

stderr.

However, if plots are generated in the process, the plots are stored in
Rplots.pdf.

Is there a way via command line arguments to change the name of the pdf
output.

There might be multiple runs of this script and it would be ideal to

store

the plot output independently.

That's the default filename if you open a PDF device.  Open it
explicitly and you can specify any file you like.

That is,

   plot(rnorm(100))

will call dev.new() which in a non-interactive session calls pdf().  If
you specify

   dev.new(file = "something.pdf")
   plot(rnorm(100))

the "file" argument will be ignored in an interactive session, but will
be used in a non-interactive one.
