A very brief question.
I have managed to put greek letters in my axis labels using expression().
Question is, is there an easier (shorter) way than typing
plot(runif(10),ylab=expression(NH[4]~(mu~M)),xlab="Time (h)")
to get the subscripts and micro sign.
Like NH$_4$ $\mu M$ would be nice :)
No, and your R version already *is* shorter:
nchar("NH$_4$ $\mu M$")
[1] 13
nchar("NH[4]~(mu~M)")
[1] 12Uwe Ligges
