Hi Gabor,
Wow, this is awesome although I eventually should learn MySQL for
integrating it on web-based DB management using PHP or Perl, this is a
very helpful tool for me to start with!
Thank you very much

Great. Regarding the web, note that there are actually quite a few R
web projects as well:

I have used rpad (www.rpad.org) which has an integrated web server right
in the R package making setup a non-issue.

Paul, what is the question? If the question is why you get this
warning message, the reason is that the 'lib' argument is missing
and install.packages is using '/usr/lib/R/library'.
If you want to get rid of the warning supply the 'lib' argument.

Hi Shubha,
genoud does not return the initial fit value. But you could easily
obtain it by passing your starting values to your function directly.
Alternatively, one can have genoud print out the entire initial

You could also try and use RSPerl (http://www.omegahat.org/RSPerl/). It
