package fdim slopeopt error (PR#6819)

thanks Andy 
last paragraph of the link you indicated 
" Bug reports on contributed packages should perhaps
be sent to the package maintainer rather than to
R-bugs. "
the maintainer (Francisco Javier Martinez de Pison.
francisco.martinez@dim.unirioja.es) has a bad email
address and therefore can't be reached.

thanks
Fred J.

Please read the last paragraph of
