[R] Plotmath isn't working for special characters

[David Stevens]

Simple expressions on plots, such as parse(text='x >= y') have been 
resulting in just a placeholder box (x box y and not the symbol) in my R 
plot labels in windows, R v 4.2.2. I haven't down an exhaustive test but 
<= and >= have this behavior.

plot(1,1,main=parse(text="x >= y"))

Has anyone else seen this?

best

David
