[R] Save multiple plots in a single pdf file when the plots are generated by a single plot command

[Debs Majumdar]

I thought that might be the case and did a couple of dev.off() even though I started a new R session. Each time I try to use the plot, it comes up with "pdf 2".

It looks like you have one too many pdf objects open. The "pdf 2" that
is printed indicates control was returned to another pdf device. Keep
doing dev.off() until you get the message "null device 1" and then try
it once again.

Best,
Michael
