[R] sample

[arun]

Hi,
They get different results:
with the same set.seed()
 x=c(3,2,6,1) 
 n=length(x)
 set.seed(1)
 sample(x,1,replace=TRUE)  
#[1] 2
set.seed(1)
 sample(x,1,replace=TRUE,prob=rep(1/n , n) )
#[1] 6


 identical(sample(x,1,replace=TRUE),sample(x,1,replace=TRUE,prob=rep(1/n , n) ))
#[1] FALSE
A.K.

Hello
If I have x=c(3,2,6,1) and n=length(x), are the following codes equivalent??
sample(x,1,replace=TRUE)    and       sample(x,1,replace=TRUE,prob=rep(1/n , n) )
Regards
