Hello, In the past I have used "expression" to include greek letters in axis labels, but this time I need to include the greek letter as part of a legend. Basically, I need to create the following vector to rename the levels of a factor:
c("Interferon-gamma", "IL-10", "IL-5"), where "gamma" obviously needs to be printed as the greek letter gamma. I have tried expression("IFN-"*gramma), but it only works when it is isolated, not as part of a vector. Any guidance would be very appreciated. Thank you, Judith ______________________________________________ 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.
