Greek letter included in a character vector
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...
