Hi.
I'm trying to get 'mu' to show up as a Greek symbol but, despite trying every
example I could find, can't get it to work. Any insights would be welcome.
This is what I'm using that works, but displays mu with the letter u.
plotTimeXMastPAR <- qplot(DT,MastPAR, data=A, xlab = "", ylab = quote(PAR (uE
~m^-2 ~s^-1)), geom="line") + opts(legend.position="none")
This is an attempt to get mu to look right but it does not work. It doesn't
fail but nothing inside the expression statement gets displayed.
plotTimeXMastPAR <- qplot(DT,MastPAR, data=A, xlab = "", ylab = c("PAR",
expression(mu, quote(E ~m^-2 ~s^-1))), geom="line") +
opts(legend.position="none")
Cheers.
