Left sided exponent in expressions

Normal exponents in expressions are done via expression("C"^13 * "some string"). However, I now need a possibility to make such an exponent on the left side, like it is needed for the correct description of Carbon-13 (example: Left sided exponent)

I need to write 13C for a figure-title in ggplot2.

Is there an expression-notation to do that? Or another way to do such a thing?

Just have a blank + superscript 13, juxtaposed with C.

ggplot() + 
   ggtitle(expression("Something having to do with "^13*"C"~" concentrations"))

If you need 13-C at the beginning of the string, you can use an empty string (expression(""^13*"C"))

This is the way that most people do it in LaTeX as well (i.e. ${}^13\textrm{C}$), although the isotope package for LaTeX states that this is typographically unsatisfactory ...
