"I also don't understand why it would be set to X11 in a plain-old R
session"

R is an open source derivative of S and S-PLUS--"S" was the "Statistics
Language"

MIT X Consortium's "X Motif" is the default output of R from its inception

R, S, S-PLUS have always made such output as its default

Suggest you just "get with the program"--thousands of R libraries are ready
for you to use, extend and create your own libraries if you like--all
leveraging the power of X11R6 --i.e. the XWindows system:
https://en.wikipedia.org/wiki/X_Window_System

By the way Micro$oft Windows is based on MIT's W--W stood for Windows--yet
another thing MicroSoft swiped and monopolized and then sued others about
whenever possible--rather than join the open source & free software movement

X11 is free & open source--all the best software is free & open
source--like Emacs Org-Mode
