[R] Greek symbols (again but more complicated)
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.

Try library(ggplot2) qplot(mpg, wt, data=mtcars, xlab = , ylab = bquote(mu~(E ~m^-2~s^-1)), geom=line) (thanks to Baptiste and David in http://r.789695.n4.nabble.com/How-to-plot-an-expression-label-with-variable-text-td2341465.html#a2341504 ) And please always use reproducible code for posting as above; your code had the data set missing, which was totally irrelevant anyway, and ggplot2 was missing.
