When I run R CMD check on my Linux machine [*], I also
do not get an error.  But here is a guess: The error
mentions \verb, and the LaTeX manual says that \verb
should be followed by nonspace character.  But in the
vignette it is followed by a space.  Maybe using \url
in the vignette could fix the error?

kind regards
