Math Expression and Variable Value in Title

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

Hello All,

I am trying to put a math expression into a plot title and at the same
time, I want a value in the title to depend on a variable that I set
earlier.

Simple Example:

n <- 20
plot(0, 0)
title(expression(paste(n[i], " = ", n)))

Obviously, I want "n_i = 20". How can I get that?

Thanks in advance,
