Matrix to data.frame with factors
Hello, Try the following. x <- matrix(sample(0:1, 12, TRUE), ncol = 4) y <- data.frame(apply(x, 2, factor)) str(y) Hope this helps, Rui Barradas Em 19-10-2012 12:04, brunosm escreveu:
Hi all, I have a matrix with 100 variables: each variable as a value of 0 or 1. What i want to do is convert this matrix to a data.frame but convert all the variables to factors (0 and 1) also. I know i can do this one variable a time but i have 100 variables... Any easy way of doing this??
