Ok I understand. I wasn't intended to look as complaining, sorry.

 It was interesting to get the pointview of a developer (thanks JC Nash).
To code a new package comprising useful but deprecated functions is a very
good advice, thanks, I will try to hone my coding skills to do so (and to
be more involved with the R community as well).

Thanks again for your feedback
