[R] binary conversion list to data.frame with plyr... AND NO LOOPS!

Happy weekend helpeRs! As usual, I'm stumped by R... My plan was to take an integer number, convert it to binary and wind up with a data.frame where each column is either 1 or 0 so I can see which bits are changing: bb-function(i) ifelse(i, paste(bb(i %/% 2), i %% 2, sep=), )

try this: x - c(36, 40, 10, 4) x.m - matrix(as.integer(intToBits(x)), byrow = TRUE, ncol = 32)[, 1:20] x.m - data.frame(x.m) # convert to data.frame x.m X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 X13 X14 X15 X16 X17 X18 X19 X20 1 0 0 1 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0
