<<This shall work. What really are values of region? What does str(eu08$region) tell you about it? If it is really factor, what are really its levels? What does level(eu08$region) show?>>
My thoughts were also that it would work, but it results in 130 column headings stripped of all rows. To answer your questions: str(eu08$region) yielded: $ region : Factor w/ 10 levels "1.Byrard",..: 3 3 3 3 10 10 10 4 4 4 ... level(eu08$region) yielded nothing, but levels(eu08$region) yielded: [1] "1.Byrard" "2.Alsat" "3.Bigur" [4] "4.Itziar" "5.Ingur" "6.Git" [7] "7.Git Balance" "8.Triage" "9.Snolunt" [10] "10.Bigntu" Thanks for your attention, Petr! -- View this message in context: http://n4.nabble.com/Subset-Question-tp1568555p1568584.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.
