[R] Help with expression

[David Scott]

I have a problem with expressions. I am trying to create a title where 
the parameter of interest is displayed as a Greek character. Which 
parameter is being considered is stored in a character variable.

As an example, if I have

param <- "alpha"

and then do

plot(0, 0, main = bquote(Parameter==.(param)))

then in the title I get "Parameter = alpha",
whereas I want the Greek character alpha.
