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]
