[R] factors levels ?
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.

Hi, see ?cut ?pretty can also help to define boundaries. Regards, Thibaut. Hi, It's just some example code.. The application is uninteresting. I am searching for some functionality.

What you are looking for is the findInterval() function. Julian W Eryk Wolski wrote: Hi, It's just some example code.. The application is uninteresting. I am searching for some functionality.
