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. -------------- John Helly, UCSD / San Diego Supercomputer Center / Scripps Institution of Oceanography, Climate, Atmospheric Science, and Physical Oceanography / +01 760 840 8660 mobile / stonesteps (Skype) / stonesteps7 (iChat) / /www.sdsc.edu/~hellyj ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
