"fontsize" option in rmarkdown ==> PDF?

Greetings. I am not able to the the `fontsize` option to do anything when
using `rmarkdown::render()` to produce a PDF document.

I've tried a lot of permutations, but here's a simple example from the
"LaTeX Options" section of:

http://rmarkdown.rstudio.com/pdf_document_format.html

The two appended code segments call for "11pt" and "16pt" font size,
respectively. So far as I can tell, the resulting PDF document is exactly
the
same in both cases.

The things of interest to me are slightly more complicated. See the end of
the message for an example of that. And note that I've tried making the
font
size 24pt, so as to eliminate any "eyeball" errors. I.e., if `fontsize`
were
doing what I want, I *would* recognize it.

Session and package information are also included below.

Any thoughts? Thanks.

The standard latex classes (article, book, and report) accepts only 3
different font sizes: 10pt, 11pt, and 12pt.

(I suppose the the rmarkdown documentation could make that more
obvious https://github.com/rstudio/rmarkdown/blob/master/R/pdf_document.R#L53)

You'll need to use a custom latex class if you want size 24pt font.
(You may also look into telling rmarkdown to use xelatex, but you'll
still need to adjust the class).

Cheers,

Carl

Thanks, Carl. I used 24pt just to make sure I could get something
that was visually distinct from the default, but I did want something
larger than 12pt.
