I have a dataframe containing X and Y. Right now, I want to create another variable in the dataframe, named Z, such that for Z = 1 for the top 10 largest value of Y and Z = 0 for the rest values of Y.
I really appreciate your help. Have a great weekend. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
