Hello all, I'm not really sure how to search for this in google/Rseek so there is probably a command to do it. I also know I could write an apply loop to find it but thought I would ask all you lovely R gurus.
I have a very long vector (length=1855190) it looks something like this 1111...2222...3333....etc so it would be something equivalent of doing: rep(c(1,2,3,4,5), c(10,30,24,65,3)) How can I find the index of where the step/jump is? For example using the above I would get an index of 0, 10, 40, 64, 129 Any help would be greatly appreciated. Cheers, Paul ______________________________________________ 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.
