Thanks for the help.
-I'm really sorry, but I'm affraid I can't publish any data in order to
allow a reproduction of the results (enterprise policies :( ).
-I'm using ols() from Design (Is there another ?)
-Does version of R influence on the behavior of the packages ? I didn't
know, I'm using Version 2.0.0 (2004-10-04), ISBN 3-900051-07-0

-I have no missing values. I previously try to use a data.frame but the
was other error message, and because of that I split the data.frame,
finally after you suggestions, I create a new data.frame and still didn't
work until I attached a the new data.frame and it works.
Thanks
