Two things: 1) the comment isn’t very clear. “Since it won’t” what? Maybe
you can rephrase. 2) Instead of deleting the “check” phase just write
(arguments `(#:tests? #f))

Quoting “Markdown” looks odd. How about just
“Markdown rendering library for R”

The quoting looks very odd. Does this mean that “Sundown” must be
available at runtime in order to use the “r-markdown” package? If this
is so, shouldn’t a “sundown” package be among the inputs of this
package?

This appears to be correct. The license headers of the files in the “R”
directory only explicitly mention “version 2”, there is no “or later”
clause. I just wonder what this means for libraries using
“r-markdown”, such as “r-knitr”, which according to your next patch is
supposedly released under “GPLv3+”. IIUC this cannot be the case.
