Or, plot(1:10, ylab = expression(N[2]*O~"concentration (ppm)")) (because of the "~", you can even do away with "expression()", but I think that would be overly sneaky.) ______________________________________________ [email protected] 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.
