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

And how to get something like a bar over a character like \bar x ?See ?plotmath, which BTW, is listed in the "See Also" section of ?text HTH, Marc Schwartz
