...a vector of breaks: > xx.y [1] -2.2000000 -0.9666667 0.2666667 1.5000000 I want to produce another vector z which contains the number of the class that each data point is in. for instance, xx[1] is between xx.y[1] and xx.y[2], so z[1] == 1 this can be accomplished via loops, but I was wondering if there is a more efficient method, please. By the way, eventually, there will be many more data points and more classes. thank you for any help! sincerely, Erin Hodgess mailto: hodgesse at uhd.edu Version 1.7.0 R for Windows
