[R] Isotopic notation in plots

[Andersson, Henrik]

I really like to use R for all my graphs, and as I work with stable
isotopes I want to have a proper chemical notation in my plots

I have looked at ?plotmath, but didn't find the answer and also searched
the R website.

plot(1:10,xlab=expression(^{14}*C))  # I want to have a superscript with
nothing in front, but it doesn't work 

plot(1:10,xlab=expresssion(.^{14}*C))  # this works, but is not
beautiful

Any ideas ?
