You could try using a string literals

The only way is to use raw HTML

Your code should look like this:

Your code looks nearly correct to me, but the "*" characters are unnecessary. In fact when I try to use "*", R throws an error.

Your use of factor to change the label names is also unnecessary, and will cause the labeler to miss the label for "R2" entirely, since you have re-labeled it "R^2".

Syntax for setting mathematical expressions in facet labels has changed between versions of ggplot, so a lot of the advice out there is out of date. The following works with ggplot 3.3.5. Construct a labeller using as_labeller and specify default = label_parsed.

In this example, I am modifying the "cyl" column of the "mtcars" data set to closely match your situation (the mutate line). Note that the names of the labeller vector must match the labels you define in factor. The values of the labeller can be anything.

The issue with the superscript numbers is that the UTF-8 codes are not contiguous, you need a translation table.

Here is one way to do it with the help of f-strings:

In Jupyter Notebook/Lab this should work:

If you prefix the expression with a 0, the compiler considers this value to be represented in the octal radix. Values in octal radix must be in the range of [0,7]. The value 9 in the 0179 expression is outside of the octal radix range.

Try the following solution to print superscript 3:

The is_digit method returns True for subscripts and superscripts. You can use a combination of int and is_digit to implement that:

It's you TEXT rule:
