superscript and subscript the same character in an expression

Question

In a plot I would like a title which should have: the string "my title is" followed by the caharecter alpha raised by `'` (i.e. alpha prime) with alpha also having the subscript G. I tried: ``` expression(paste("my title is ",alpha^{"'"}[G],")")) ``` but the above code raises alpha to the power `'G` . How do I superscript the `'` but subscript the `G` ?

Accepted Answer

Either of the following would do the trick:

```
alpha[G]^"'"
{alpha^{"'"}}[G]
```

They are typeset slightly differently, so pick whichever you prefer.
