[R] How to plot "greater than" symbol on the x-axis

[Henrik Bengtsson]

What have you tried this far and what part does not work?  If you
forget for a moment the fact that you want to have ">=1", ">=2", ...
can you do what you want with plain "1", "2", ...?  Telling us that
helps us help you.

Are you asking for the labels on the *tick marks* on the axis?  Right
now it sounds like you are asking for *the label* on the x axis, but
the part that you want multiple ones is confusing.

plot(1:10, xlab="1");

is different from:

plot(1:10, axes=FALSE);
axis(side=1, at=1:10, labels=1:10);

To add ">=" to the latter case, this works:

bquote("" >= 1:10)
labels <- lapply(1:10, FUN=function(x) substitute(>= t, list(t=x)));
plot(1:10, axes=FALSE);
axis(side=1, at=1:10, labels=labels);

I did not make it work. Do you know how to make it? The expression("">=1"") did not work, and paste(expression("">=""), 1)
