Oddly, the first time I now open this file and execute the block, the
file shows up on the Desktop. If I delete it and re-execute, it puts
it in C:/Users/username/Documents! Why would this be? I used =setwd()=
above just to make sure R was elsewhere than the Desktop because I
have another file in which I thought :dir was working properly, but in
fact it was just the default R dir and so the plots were going there
anywhere. Changing the working dir caused the :dir on that block to
reveal that it wasn't working after all.

In the above, even removing the =setwd()= line produces the same
behavior. First time creates file on Desktop, subsequent times puts it
in Documents.
