Hello,
aa<-c(1,1,2,2,3,3,4,4,5,5,6,6) bb<-c(56,56,33,33,53,53,20,20,63,63,9,9) cc<-data.frame(aa,bb) uniquedf <- unique(cc) View(uniquedf) Why does the column "row.names" appear in the new dataframe and how do I get rid of it. "uniquedf$row.names <- NULL" does not seem to work. For what I'm doing this is a useless column and can cause confusion and/or problems for subsequent merging/filtering etc. Thanks. -- View this message in context: http://www.nabble.com/Remove-row.names-column-in-dataframe-tp18050179p18050179.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.
