Hi, everybody. This was an interesting discussion last time and it helped me a lot.
Could you please have a look at some feature and tell me why it was designed this way (my questions are under #########) > x = c(1, 10) > y = c(99, 55) > d <- data.frame(x = x, y = y) > d x y 1 1 99 2 10 55 > add <- data.frame(x = 14, y = 99) > add x y 1 14 99 > d <- rbind(d, add) > d x y 1 1 99 2 10 55 11 14 99 ######### it would be more natural to index the rows: 1,2,3 instead of #1,2,11 ?! > > d[3,1] [1] 14 > d[11,1] [1] NA ######### especially if index '11' is not functioning... > > add1 <- data.frame(x = 10, y = 87) > d <- rbind(d, add) ######### now I would think that the next index should be 21, BUT: > d x y 1 1 99 2 10 55 11 14 99 12 10 87 ######### so what is the intuition of such indexing? -- Svetlana Eden Biostatistician II School of Medicine Department of Biostatistics Vanderbilt University ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
