Change the font size and the space between code and output in the generated beamer file?

Change the font size and the space between code and output in the generated beamer file?

I use rmarkdown::render to convert a Rmd file to a beamer pdf file. I 
learned from a previous post that I can use "fontsize" in YAML metadata to 
set the fontsize for the whole PDF file generated by pandoc.

However, is it possible to set the font size only for code and output of 
the code? For example, I would like make the code smaller than the text.

Related to this issue, will the space between the code and its output 
reduce accordingly if I reduce the font size? If not, how can I reduce the 
space between the code and its output? (I am not sure if this question is 
related to pandoc, if the spacing does not depend on font size).

You might try with --latex-engine=xelatex, then you can adjust the
following variables:

mainfont
sansfont
monofont

Note that they will take  system font names, rather than the special
font names used by regular pdflatex.

Thanks for the advice. I will take a look.
