Is it possible for users to add custom paper size definitions to the "Save plot as..." configuration dialog box? Here I'd like "A3" to appear inside the "PDF size:" select field.
I know how to add my custom size (just double the A4 dimensions), but I prefer to have a persistent "A3" size in the selection list. Simply to avoid entering the A3 every time I want to print a larger plot.
The default is the devise size, or dimensions of RStudio's plot window. I am not aware of how to change this default other than suggest an IDE feature request, or offer a contribution to where this is handled (SavePlotAsPdfDialog.java).....
A feature request of "first default to device, then default to last used, unless the R-session has been reset" seems pretty reasonable to me. But others may disagree. Creating an enhancement request via github issues is a good way to start that discussion.
But if you are saving plots so frequently as for this to be a hassle, I'd suggest looking into saving your plots via code.
ggplot2 - look into your options with ggsave (if a ggplot). Device would obviously be "pdf" and width, height, and units set to A3.
base-r - And here's a discussion with base R, using pdf, some plotting, and dev.off.
With this question I just wanted to make sure that there was an option somewhere that I didn't know about.
Thanks for that detailed answer, maybe I'll add an enhancement request, then.
I've already saved plots will ggsave(), this is easy and convenient.
But sometimes when I go through a list of older plots inside the rstudio "Plots" pane, I discover some older plot that's worth saving/printing for some reason. In this case often the codechunk containing the ggsave call has been changed in places, and undoing the changes is not really possible. Then I wished printing as A3 would be easier.
