Hi All,
I am having trouble getting a complex subscript to work. I'm sure
it's possible. Here is what I have:
ylab=expression(paste("log ",L[peak]," [erg ",s^{-1},"]")),
I would like to have the subscript read "peak,gamma" where the
gamma would be the greek symbol. I do want the comma to show as
well.
(I do not see a gamma so using your verbal dsecription. The rest of your intent is muddied by the multiple subscripts. It's always difficult to know what people are thinking when they construct plotmath expressions and do not describe their full intent in English. Here's my guess: ylab=expression(log~L[peak*","*gamma][~erg~s^-1]) plot(1,1,ylab=ylab) The paste function is rarely needed and generally confuses the intent of the author. Using "~" and "*" generally results in more comprehensible expressions.
And it might look more "physics"-al if you had a "cdot" between the units: [~erg %.% s^-1]
