How can I change the font size of the the math formulas in Rpres? [Editor's note: 'Rpres' is the file extension used by RStudio for its "Presentation" files. It's apparently been adopted by users as shorthand for that section of the IDE.] A similar problem is faced in Code box size and font size in RPres, but it does not solve the problem with math formulas, that are not part of a chunck of code separated from the text, but are a chunk of LaTeX code.
Please consider, for example, this section of a slide produced with the default setup:
The average height is 175cm, with a standard deviation of 10.
The z-score for a student 163cm is given by the formula:
$$z = (x - \mu)/\sigma$$
where $x$ is the student of our interest, $\mu$ is the distribution mean of
the school and $\sigma$.
Math formulas in RPres documents and Rmarkdown documents are LateX chunks of code embedded in the Rmarkdown document.
Hence, the font size of a math formula or, more generally, of LaTeX text, can by modified with an argument ranging from
