[R] Monospaced font not shown correctly (Xubuntu 20.04)

[Viechtbauer, Wolfgang (SP)]

Ah, nevermind. X11Fonts() is only for Xlib.

I'll see if I can figure out how to get 'fc-match Courier' to point to a otf/ttf font. I guess this is explained here: https://www.freedesktop.org/software/fontconfig/fontconfig-user.html

Best,
Wolfgang
