Subject: How to use strings from a data.frame as the argument of an expression() for plot
Thanks for your response; one more thing: Is it
possible to use a data.frame
for the same effect, as these values are associated
with some others (I could
of course use them separately, but merging them in a
data.frame should be
possible in R)?
