Actually, with your definition of Sinput

\DefineVerbatimEnvironment{Sinput}{Verbatim} {
frame=lines, label=\textrm{\bf R code}, numbers=left,
framesep=10pt, fontshape=sl, commandchars=\\\{\}}

you can have \label{} in the verbatim environment. I haven't tried this 
but something like

help()   # \label{line1}

might work, and I believe there is a switch that suppresses the comments 
for Sweave
