[R] LaTeX in R

[Mario Maiworm]

I finally got everything plotted as I had planned. So, thank you again.
Sundars suggestion looks more flexible when it comes to large numbers of
categories (i.e. sigmas). In the plot I will be using, there are 3 sigmas...
I am keen to learn about that bquote and substitute stuff. I will definitely
take a look at your newsletter contribution, uwe.
The ';'s were intended to ease the mail2console copy-and-paste, as some mail
programs take control of your linebreaks.
Mario.
