I wish to write a single word in italic in the axis title of my graph using ggplot2. I am trying to write something like this: "The alpha-male percentage", where alpha is in italic.

I have tried the following within my plot code:

ylab(expression(paste("The", italic("alpha"),"-male percentage"))

yet "alpha" is still not in italic. Could someone help?

I do not see why this should not work (in fact it does work for me). Please provide a minimal reproducible example. – Martin C. Arnold Jul 27 '16 at 13:43
You are right, it does seem to work now! Sorry for that. While we are at it, any way of incorporating a line jump (i.e. "/n") in the above expression before "The"? – ykl Jul 27 '16 at 14:13
you can get niceer spacing without the paste... `expression("The"~italic("alpha")-"male percentage")` – user20650 Jul 27 '16 at 20:20
