[R] Question about random sampling in R

I looked up the help file on sample(), but didn't find the info I was looking for.

When sample() is used to resample from a distribution, e.g., bootstrap, how does it do it? Does it use an uniform distribution, e.g., runif(), or something else? And, when the help file says:"sample(x) generates a random permutation of the elements of x (or 1:x)", would I be correct if I translate the statement as follows: it means that the order of sequence, which was generated from a uniform distribution, would look like a random normal distribution.
