Hello R User, I have a data set where subject( Id) are frequently measured. For example, the size of the data set is 75 by 2 and has following frequency distribution.
id freq 1 30 2 20 3 25 I want to create a variable (say seq) containing sequential count for each id. I mean variable seq should be as ( 1,2,..,30, 1,2,...,20, 1,2,...,25) I use following code but did not work. Any suggestion is much appreciated.. sim<-rep(NA, 90) for (i in 1:3){ d[i]<-seq(1,a[i,2],by=1) sim[i]<-as.vector(c(d[i]) } Thank you, Bibek ______________________________________________ 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.
