I'd like to add a "greater than"-sign to an axis label.
The text shown should be `cumulated frequency p(>p[f]))`

I tried (amongst others):

```
title(mgp=c(2.50, 1, 0), cex.lab=1.25, xlab = expression("cumulated frequency" ~ p(>p[f]))) # xlab

```

But none of my trials worked - where is the mistake? Without having the `>` it works fine:

```
title(mgp=c(2.50, 1, 0), cex.lab=1.25, xlab = expression("cumulated frequency" ~ p(p[f]))) # xlab

```
