 |   Hi.
 |   I'm working in a project about web-users behaviour analysis. In a few
 | words, it consists on:
 | - log-files recopilation and pre-analysis
 | - basic stadistics extraction (pages most visited, session lengths, etc.)
 | and on-line report generation in a web-viewable format
 | - more advanced analysis for web-users characterization

I would recommend perl (or rexx) for the first task.  R is basically a
vector-oriented programming language with its text-file analysis and
parsing possibilities, and a large number of statistical functions.
You can definitely do everything with text files in R too, but it is
perhaps faster and more straightforward in perl.

If you already have the data in a easily readable form (ascii tables,
xml), then it is easy to continue with statistics with R.  I am not
familiar with statistical functions in perl but I am sure they lay far
behind from those in R.

So, I guess you should use perl at least for the first step, and
depending on the complexity of the ,,more advanced analysis'' either
continue with it or switch to R at the second step.  BTW, R is using
perl heavily for installation and package management.

Perhaps it helps.
