Hello,


I have a simple question on the text() method in plots, e.g.:

text(3,4,adj=1,cex=1.0, expression(alpha == beta))

I know there exists a lot more like frac(), etc which could be used for
expression. But a help(frac) doesn't return any results - where do I
have to look for a documentation of possible text commands?

More in detail I'm searching for how to set an index like mu_{1} and
mu_{2} ? And how to get something like a bar over a character like \bar x ?


TIA,
 Lothar
