[R] How generate random numbers from given vector???

[Muhuri, Pradip (SAMHSA/CBHSQ)]

Hello,

The other options is to use the sample() function.

test2 <- matrix (rep(sample(number1, size = 5), times=3), nrow=3)

Hello,

You don't need the loop, the sample() argument 'size' is there for that.
See 'sample.

number <- c(0,1,3,4,5,6,8)
rsidp <- function(n) sample(number, n, replace = TRUE)
rsidp(5)

Hope this helps,
