Browse[1]> str(datalist2[[1]]$dataset$Results[[j]]$Results[[time]]$Sweep) int [1:10307] 2 1 3 1 5 6 3 1 0 2 ... as you can see the two vectors differ only in one element. As the sample is quite large it would be the same if I ignore the one extra element. There are times though that the missing elements can be 2 or 3 (but always the number is small enough so to be ignored) The major concern is that this "difference" can be either on the fist vector or either on the second vector. If I try to solve that with simple if statements the code gets too much of spaghetti... Is there a simple way when there is this length difference either to a. Ignore the extra elements -or- b. Add the elements missing to the vector with the smaller length( one can just duplicate some of the existing values to reach the needed length) How I can do either a or b? I would like to thank you in advance for your help Regards Alex [[alternative HTML version deleted]] ______________________________________________ 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. ______________________________________________ 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.
