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

[arun]

Hi, 
Try this: 
number1<-c(0,1,3,4,5,6,8) 
 rsidp<-function(x){ 
 y<-sample(x,5,replace=TRUE) 
 y 
 } 
 rsidp(number1) 
#[1] 3 0 6 8 4 
 rsidp(number1) 
#[1] 1 8 8 6 4 
 rsidp(number1) 
#[1] 8 3 6 6 6

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

I wanna generate random numbers from a vector...

for example number<-c(0,1,3,4,5,6,8)
so

rsidp<-function(x){
    i=0
    for (i in seq(1:x))

    {y<-sample(number,x, replace=T)}
    return(y)
}
so all random numbers have to be from vector "number";
so if I type rsidp(5)..... it has to give me 5 random numbers except 2,7,9
(because they are not in the vector "numbers"). help me plz with it (((
