Dear all, Could you please help me how to get the output as I described in the following example?
x<-c(543, 543, 543, 543, 551 , 551 ,1128 ,1197, 1197) diff<-x-lag(x) diff [1] NA 0 0 0 8 0 577 69 0 How to index the occasions in x repeatedly if the diff<15? if diff>=15, it will give a new index. I want the output be like y. y<-c(1,1,1,1,1,1,2,3,3) Thank you so much, Lijun Zhao (PhD Candidate) Nutrition and Metabolism Level 7 SAHMRI North Terrace Adelaide 5005 Ph : +61 8 8128 4898 e-mail: lijun.z...@adelaide.edu.au<mailto:lijun.z...@adelaide.edu.au> or lijun.z...@sahmri.com<mailto:lijun.z...@sahmri.com> [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
