[R] Q: obtaining non-transparent background in png

But following that logic, changing the size of the plot shouldn't work either.

I don't think you can have it both ways. I.e., either it's OK to change the
size and the background, or it's not OK to change either of them. There's
no way to deduce from the word "copy" that you're allowed to change some
things but not others; I think that's where the confusion enters.
