[R] Math Expression and Variable Value in Title

[Salvatore Barbaro]

An alternative but also higly recommendable way is the use of the 
psfrag-package in your LaTeX-file. It is furthermore very simple in use.

Type

plot(1:10, main="test")

in your LaTeX-file you insert in your figure-environment the command
\psfrag{test}{$n_i=20$}
before you call the \includegraphics{}

best regards

yours
