roxygen2 tries to do the right thing here. As defined in "Parsing Rd
files" [*], \code{} blocks are supposed to contain syntactically valid
R code. When something that is not valid R is given in a Markdown code
block, roxygen2 should not output \code{}, so it outputs \verb{}.

Also, unlike in LaTeX as understood by tools::parseLatex(), \verb{}
blocks use the {} braces in R documentation, and are understood
correctly by tools::parse_Rd(). Perhaps you also need tools::parse_Rd()?
