I was using the hist() function to create a frequency table of some network traffic data. The range in values is rather large, from 0 till just under 10e12. Calling hist(x, breaks=c(0,1000,1e6,1e9,1e12),plot=F,freq=T) causes hist() to return : $breaks [1] -1.0000e+05 1.0100e+05 1.1000e+06 1.0001e+09 1.0000e+12 Is this recalculation of the breaks by hist() intended?

How many zeroes are there? If you got rid of them, a log transformation might help you. Also, have you considered looking at the distribution of the times between packets (or bytes)?? There are some interesting theoretical models for the distributions of times between packets. I've got a few books on the subject, but they're at home. E-mail me off list if you're interested. -- znmeb at aracnet.com (M. Edward Borasky) http://www.aracnet.com/~znmeb How to Stop A Folksinger Cold # 4 "Are you going to Scarborough Fair?"
