Hi everyone. I want to transpose a data frame. Lets say the following DF:
df = data.frame(matrix(ncol=4, nrow = 10)) df[,1] = c(rep(1,5),rep(2,5)) df[,2] = c(rep('a',4),rep('b',3),rep('c',3)) df[,3] = c(letters[5:14]) df[,4] = runif(10) I would like to form a data frame with each line corresponding to colon X1 and create a variable with columns X2 and X3. This would give me a DF with the following columns. / *X1, ae, af, ag, bi, bj, bk, cl, cm, cn* /1 n n n n n NA NA NA NA NA 2 NA NA NA NA NA n n n n n where n = numbers in column X4. I'm not sure how to manipulate my DF to rearrange it so I keep var X1 but I create 10 new variables with coloumns X2 and X3 with values from X4. I hope I have been clear enough! Thank in advance for your insights, Phil -- View this message in context: http://r.789695.n4.nabble.com/Matrix-transposition-tp4599219.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.
