Here's one possible way (assuming the two data frames have the same number of columns):
> d1 <- data.frame(A=1, B=2, C=3) > d2 <- data.frame(X=1, Y=2, Z=3) > res <- c(d1, d2) # This cbind them and turn into a list. > idx <- as.vector(matrix(1:(2 * ncol(d1)), 2, byrow=TRUE)) > idx [1] 1 4 2 5 3 6 > as.data.frame(res[idx]) A X B Y C Z 1 1 1 2 2 3 3 HTH, Andy From: Matthew Scholz > > Dumb newbie question: I've searched the manual, R help and > the mailing list > archives, but can't seem to find the answer to this simple > problem that I > have.
