I am wondering how to fix the random seed of sample function in R.
An easy example is here:
set.seed(1)
tmp <- c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
sample(tmp, size = 3) # (*)
#[1] 9 4 7
sample(tmp, size = 3) # (**)
#[1] 1 2 5
sample(tmp, size = 3) # (***)
#[1] 7 2 3
sample(tmp, size = 3) # (****)
#[1] 3 1 5
# retry set the random seed
set.seed(1)
sample(tmp, size = 3) # (*)
#[1] 9 4 7
sample(tmp, size = 3) # (**)
#[1] 1 2 5
sample(tmp, size = 3) # (***)
#[1] 7 2 3
sample(tmp, size = 3) # (****)
#[1] 3 1 5
Then, when I repeat the sample function, the returned values change, although pattern of the change is uniform.
I cannot understand why sample function is differently affected from the set.seed. How can I fix the return from sample function?
Thank you for your time to spend to read this question.
