[R] greek letters, text, and values in labels

[Adrian Dragulescu]

Hello,

I want to have a title that will look something like:
"Results for \theta=2.1", given that I have a variable theta=2.1, and
\theta should show on the screen like the greek letter.

I've tried a lot of things:
theta <- 2.1
plot(1:10, main=expression(paste("Results for", theta, "=", eval(theta))))

or using bquote
plot(1:10, main=paste("Results for ", bquote(theta == .(theta))))

or using substitute, etc.  I could not make it work.  This should be easy.

I would appreciate your help.

Thanks,
Adrian
