Peter, Thanks for your reply and comments. I had to go back to the R Bugs database and review his filings. Once I did, it triggered memories of the reports and some of the associated replies. He also filed some older ones under [EMAIL PROTECTED] I do agree on his vigor with respect to these issues, especially since both sides benefit from the interaction. It's good to see the cooperation. As I mentioned in my initial post, it can be helpful to folks to know that it is taking place. While one might not indicate that Gnumeric has any type of "Good Housekeeping Seal of Approval" imprimatur from R Core, it is good to see that the Gnumeric team and presumably Morten specifically, are motivated to enhance their application in this fashion by leveraging the expertise here. At least at this point in comparison, it would seem that the OO.org folks are more focused on Excel compatibility in Calc to a fault, which can become problematic on a variety of levels. At least they seemed to have avoided the RAND() bug in Excel 2003...
