Hi all, In a data set I have group(GR) and two variables x and y. I want to remove a group that have the same record for the x variable in each row.
DM <- read.table( text='GR x y A 25 125 A 23 135 A 14 145 A 12 230 B 25 321 B 25 512 B 25 123 B 25 451 C 11 521 C 14 235 C 15 258 C 10 654',header = TRUE, stringsAsFactors = FALSE) In this example the output should contain group A and C as group B has the same record for the variable x . The result will be A 25 125 A 23 135 A 14 145 A 12 230 C 11 521 C 14 235 C 15 258 C 10 654 How do I do it R? Thank you. ______________________________________________ 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.
