R help - Aug 2014 - Possible pair of 2 binary vectors

Hi,

Let say I have?2 binary vectors of length 'd', therefore both these
vectors can take only 0-1 values. Now I want to simulate all possible pairs of
them. Theoretically there will be 4^d possible pairs.

Is there any R function to directly simulate them?

Thanks for your help.

Dear Ron,

What about this?

set.seed(123)
d <- 4
x1 <- sample(0:1, d, TRUE)
x2 <- sample(0:1, d, TRUE)
x1
x2
expand.grid(x1 = x1, x2 = x2)

See ?expand.grid for more information.

Best,
Jorge.-
