I came up with this solution, > cbind(dat, dat[, 1:3]^2) X1 X2 X3 X4 X5 X1 X2X3 1 0.72776481 -1.1332612 -1.9857503 0.46189400 -0.09016379 0.529641625 1.28428102 3.9432044 2 0.05126592 0.2858707 0.9075806 1.27582713 -0.49438507

[R] How create columns for squared values from previous columns?

Dear R list, I am am a little unsure what is the best way to approach this. I suppose I have > dat <- matrix(rnorm(30), ncol = 5) > dat <- data.frame(dat) > dat X1 X2 X3 X4 X5 1 -1.1317 -0.87868106 -0.33000492 1.5241765 -0.92483388 2 -0.56168006
