Hello, I have a matrix with 4000 rows and 8 columns with 1 and zeros Every 1000 rows comes for a different rule, f1,f2,f3,f4.
1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 .... 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 ... 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 0 ... 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 How can I extract 4 matrices each one containes 1000 elements from a certain rule,since i want to a) choose between f1, f2, f3 and f4 at random according to the probabilities p1, p2, p3 ,p4 (it is assumed p1+p2+p3=1). b) sample 1 value from whichever of f1, f2, f3 ,f4 was chosen Thanks a lot Evgenia -- View this message in context: http://www.nabble.com/Split-a-matrix-for-mixture-distribution-tp15663106p15663106.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
