% used for comments

[vnijs]

% treated as a comment symbol in Rmd files (i.e., text after the % is grayed out) but will not be when evaluated by knitr

[randy3k]

it is because the latex syntax has been imported to Rmarkdown, we may need to tailor make the latex syntax for Rmarkdown.

My best suggestion for the moment is to use \% if you want to show the percentage sign.

[vnijs]

It actually shows the % sign just fine already. In fact % would print % when passed to knitr. It just seems that % is used by R-box as comment indicator anywhere in an Rmd file, not just within a formula (e.g., $…$ or $$…$$). Presumably this is defined in the syntax file for Rmd.

The comment is anywhere since the latex syntax is imported anyway....

This is solved in the latest RMarkdown syntax.
