Simple expressions on plots, such as parse(text='x >= y') have been

<= and >= have this behavior.

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

Has anyone else seen this?

 ????? What's your "sessionInfo()"?

Hello,

I can reproduce the problem in RGui, R 4.2.2 on Windows 11.
Any of the following solved it.

plot(1,1, main=bquote(x~"\u2265"~y))
plot(1,1, main=expression(x~"\u2265"~y))

Hope this helps,
