[R] Plots: I've deleted axes, now to delete space

[Adele_Thompson at cargill.com]

Re-sizing within the dev command works well. I'm not sure why I would need the dev.off(). I have the plot commands run. Then I have the dev.copy2pdf command. 
Thanks again for your help.

If your goal is to end up with a pdf file, then I would suggest creating the pdf file directly using the pdf function (you can specify height and width in the function) then run your commands to create the plot and use dev.off() to finish.

You often get different results when writing directly to a file vs doing one of the dev.copy because of some different settings.  In general the dev.copy approach can be a quick and easy solution for a simple graph, but plotting directly to the file tends to work better if you want a quality graph in the file.

I am outputting the plot to a pdf file using the code:
dev.copy2pdf(file="testing.pdf")

The plots are too small though unless I first manually increase the size in
R and then use the dev.copy command. Is there a way to automatically
increase the window size? I tried fin and din, but those do not seem to work
or they only increase the size to a certain degree, even though I can
manually increase it to fill my screen.
