Hello,
I am unable to get the greater-than-or-equal-to symbol (?) in a legend.
I am able to get pi, squares, sqrt, but not this particular symbol. Can
anyone tell me what I am doing wrong?
legend(locator(n=1), legend = c("Observed", expression("Area <
5"* m^2),
expression("Area >= 5"*m^2)), pch=c(1,16,4), bg="white")
Much thanks in advance,
Krista

I suspect expression(Area >= 5*m^2) is what you intended. -- Brian D.
