Hi All I am really very interested in starting to use R within our company. I particularly like the open source nature of the product. My company is a medical research company which is part of the University of London. We conduct contract virology research for large pharma companies. My question is how do we validate this software? I wonder if anyone else has had the problem and might be able to comment.

Dear R user, I'm wondering if anyone was succesful in compiling R under hpux 10.20 I couldn't compile verion 1.2.1 or 1.3. I asked this question two weeks ago, but nobody replyed. Looks that not many people are using hpux machines.
