A question about this to R-Devel generated replies from Peter Langfelder and David Winsemius, who noted that it worked fine under Ubuntu 18.04 (supposedly with R 3.15.2 -- probably R 3.5.2, but I'm not sure).

You should be sure.

With R version 3.5.1 (2018-07-02) -- "Feather Spray" on OS X 10.11.6 I am unable to reproduce. My Mac hardware is considered well past (Apple) end of life despite its functionality, so I cannot upgrade my OS. I'm attaching the file that is the result so Spencer can view it, although I suspect it will be scrubbed by the mail-server.

I'm not 100 percent sure, but I think I was able to control the font size with the cex and cex.axis arguments with those earlier versions of R and macOS.
