Eric, thanks for quick reply. at first look I thought it is what I need, but, unfortunately, it doesn't applied to original data - it creates new data with loosing original indexes ! I want to keep indexes of original data, but replace original data with $mids of corresponding $breaks.
So, if I have z = 1:10, t=hist(z,plot=F) > z [1] 1 2 3 4 5 6 7 8 9 10 > t$breaks [1] 0 2 4 6 8 10 > t$mids [1] 1 3 5 7 9 I want z=c(1,1,3,3,5,5,7,7,9,9) Oleg On Mon, 29 Mar 2004, Erin Hodgess wrote: > Hello Oleg! > > Do you mean something like this, please? > > z <- rnorm(15) > > z > [1] -0.36888946 0.34271755 -0.47761843 -0.58402557 0.05393014 0.69234710 > 2.04861420 1.41823938 -0.57638598 1.51090023 > [11] -0.71616401 0.19227347 -0.19348506 -0.63082326 -0.64346621 > > z1 <- hist(z,plot=F) > > z1$breaks > [1] -1.0 -0.5 0.0 0.5 1.0 1.5 2.0 2.5 > > table(cut(z,z1$breaks)) > > (-1,-0.5] (-0.5,0] (0,0.5] (0.5,1] (1,1.5] (1.5,2] (2,2.5] > 5 3 3 1 1 1 1 > > Hope this helps! > Sincerely, > Erin Hodgess > Associate Professor > Department of Computer and Mathematical Sciences > University of Houston - Downtown > mailto: [EMAIL PROTECTED] > > > > From: Oleg Bartunov <[EMAIL PROTECTED]> > > > I have numeric vector z and I want to factorize it using z$breaks > which I got from histograms breaks.
