Following up my earlier reply, and more in line with your precise question above: alnlength<-rchisq(1000,4) hist(alnlength,breaks=0.25*(0:100)) j<-density(rchisq(1000,4)) lines(j$x,1000*0.25*j$y) Best wishes, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <[EMAIL PROTECTED]> Fax-to-email: +44 (0)870 094 0861 Date: 13-Dec-05 Time: 15:59:50 ------------------------------ XFMail ------------------------------ ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
