Hello everyone, I have two vectors having only one element different: vector1 vector2 vector1
TWC TWC TWC VFC TWX NA VIA/B VFC VFC WHR VIA/B VIA/B WPO WHR --------->>> WHR WYN WPO WPO WYNN WYN WYN YUM WYNN WYNN NA YUM YUM In that case, in the first vector, the value twx is missing . What I want to do is doing the following avoiding loop: putting the NA row in front of the TWX row as this would be the row where the value is missing. I don't know if there is any function doing this. I thought about using a which() function to retrieve all the missing elements index ( twx, 1 here) and insert them in the right index in the first vector but how can I insert in a vector, is there an appropriated function? thank you ----- Anna Lippel -- View this message in context: http://n4.nabble.com/Finding-the-difference-between-two-vectors-tp1460020p1460020.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.
