double subscripts with Greek letter

Thanks, Erin! This works well.
Hello!

Here is a solution:

plot(1:10)
xa <- expression(A[list(alpha,beta)])
title(xa)

    Hi all,

    I have a question which seems trivial but simply cannot figure out its
    solution.

    I want to type A_{\alpha,\beta} in the title of a plot. Uwe once
    pointed
    out a solution

    expression(A[alpha*beta])

    But the output of the above command does not include the "," in the
    subscript. Is there a way to solve my question? Thanks so much!

    Regards,
    Jeff
