I totally agree! I think that sw <- data.frame(Fertility=1:5) sw$Fert[1] <- 10 should work either like sw$Fert2[1] <- 10 i.e. create new column, containing just 10. or like sw$Fertility[1] <- 10 i.e. replace the 1st item in sw$Fertility by 10. -- View this message in context: http://r.789695.n4.nabble.com/Assignment-of-individual-values-to-data-frame-columns-intentional-or-unintentional-behavior-tp2315105p2315641.html Sent from the R devel mailing list archive at Nabble.com. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
