One other suggestion:  define your own \doi{} macro.  The current 
definition (from R_HOME/share/Rd/macros/system.Rd) is

\newcommand{\doi}{\Sexpr[results=rd,stage=build]{tools:::Rd_expr_doi("#1")}}

You could make a two-argument variant on this.  You could even submit it 
as a patch on Bugzilla if you think others would like it.
