Subject: [R] Greek letters on title

Hi all,

I want to plot a series "x" and I want to put on title "Time evolution with
alpha=0.2", e.g.,

plot(x, main="Time evotion with alpha=0.2",col="orange")

Is there any posibility to put the greek letter and avoid  written the word?

Many thanks in advance.
