New feature to allow ggsave to save multiple plots to separate pages of pdf

[mpage21]

It would be super great if ggsave() could save multiple plots to the same pdf (on different pages).

I think ideally, the plot argument would be able to be passed a list. Same with the width and height, so that you can specify that for each plot.

For what it is worth, I have a ggsave() wrapper function called map_ggsave_ext() in my maplayer package that does this. I'm using gridExtra::arrangeGrob() or qpdf::pdf_combine() (depending on whether the plot is created using patchwork which is incompatible with the gridExtra method). It would be great to see something similar incorporated into ggsave.

Is there an update to do this now, using ggsave() ?

This hasn't been implemented yet. I've played around with this, but as far as I can see it is not so difficult to do this, but the difficulty lies with doing it cleanly and with backward compatibility.
