Plotmath isn't working for special characters

# 
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?

Also works for me on a Mac Ventura in the RStudio graphics device. Just for

plot(1,1,main= quote( x >= y ))
work? I shouldn't think so, but ...

plot(1,1, main=quote(x>=y))
produces the symbol for me.
plot(1,1, main=parse(text="x>=y"))
also produces the symbol.

Here's a recently fixed bug that may be related:

Does the R-patched build work for you?

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,

Rui Barradas

A more extensive test (no=produced an empty box on the plot, yes=produced the intended plotmath result). It appears that plotmath is not producing the special math characters. Greek symbols are produced. I'll try to reinstall R and report back.
