thanks for your extensive info, Petr ! I guess you are right that i should not try to put to much time in R when a simple C application is faster.
but there are 2 reasons why I would still try it : - i'm not a statistics or data-analysis expert. I do not know sufficient math to work our fitting algorithms in C. So i would still spend a lot of time researching the underlying math. I hope that R will solve this for me - I don't want my collegues (who are not programmers) to start asking me every little thing. I hope that, by showing them this analysis in R, they will learn some of it themselves and leave me alone :-) I will look into your sample as soon as i find the time ! thanks again ! jeroen ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
