Thanks for your help.
I should have been more clear in my initial e-mail. I shouldn't have used
'alpha' or 'beta,' to avoid confusion with them as Greek symbols. I should
have stated something like:
O foo O abcd O John
While I'm familiar with using legend to make the filled boxes, I'm
interested in creating a one line "legend" of sorts, but manually using
text() with both data symbols defined by pch and text on the same line. Or
is this not possible? I guess at the end of the day, I could use both
points() and text().
Thanks,
Andrew
