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

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
A.K.

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, Rui Barradas Em 25-10-2012 20:24, Rlotus escreveu:> 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 ((( > > > > > > > > -- > View this message in context: http://r.789695.n4.nabble.com/How-generate-random-numbers-from-given-vector-tp4647447.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
