Hi, It's just some example code.. The application is uninteresting. I am searching for some functionality. X <- rnorm(100) //my data Y <- seq(-3,3,by=0.1) // bin boundaries. Now I would like to generate a - list of factors, length as X... i.e.: all values in the range [-3,-2.9) have the same factor... [-3,-2.9) etc. I would assume R has such a function but I cant recall which one it is. -- W. Eryk Wolski

Hi, see ?cut ?pretty can also help to define "boundaries". Regards, Thibaut.> Hi, > > It's just some example code.. The application is uninteresting.
