Are you sure this is coming from a vignette?  It looks like it would be 
from an Rd file or DESCRIPTION:

The \Rhref macro is defined in Rd.sty.  There's a LaTeX \doi macro in 
jss.cls, but it doesn't use \Rhref.  On the other hand, the automatic 
conversion of the DESCRIPTION file uses it in the 
tools:::.DESCRIPTION_to_latex function.
