"size" option with highlight in pdf

[Carl Boettiger]

Hi folks,

Does knitr still support the 'size' option in chunk options in .Rmd, or does this only work in .Rnw files?  (see described on Yihui's knitr page, which is a bit unclear as to where this applies) http://yihui.name/knitr/options/

Even with the highlight package installed (suspicious that the feature is deprecated since highlight is not even suggested by knitr anymore), I don't see any effect in my pdf output when using the 'size' option in a .Rmd that is rendered to pdf by rmarkdown.  (Haven't tried a .Rnw)

If not, is there a different way to control the font size of a code chunk in pdf output that anyone can recommend?

Thanks!

Sorry, but the 'size' option only applies to .Rnw (LaTeX) documents.
I'll update the doc shortly.

For R Markdown v2, you probably need to redefine a certain LaTeX
environment that Pandoc uses, and put the definition in the LaTeX
preamble via the in_header option in YAML:
