Multiple different random samples in R

Question

I'm new to R and I've got a question:

choice <- c(TRUE, FALSE, FALSE, FALSE)
rep(sample(choice, size = 4, replace=FALSE), times = n)

always repeats the same vector, eg (FALSE, TRUE, FALSE, FALSE)

However, I want to have n different random samples of the vector choice in a new vector (replace must be FALSE, because only 1 in 4 elements should be TRUE).

Which function should I choose? I'm not allowed to use for-loops.

You can use replicate . It returns a matrix, which you can then turn into a vector.

choice <- c(TRUE, FALSE, FALSE, FALSE)
n <- 3
set.seed(42) # for reproducibility
as.vector(replicate(n, sample(choice, size = 4, replace=FALSE)))
#[1] FALSE FALSE  TRUE FALSE FALSE FALSE FALSE  TRUE FALSE FALSE  TRUE FALSE
