Hello, The other options is to use the sample() function.
test2 <- matrix (rep(sample(number1, size = 5), times=3), nrow=3) Pradip Muhuri ________________________________________ From: r-help-boun...@r-project.org [r-help-boun...@r-project.org] On Behalf Of Rui Barradas [ruipbarra...@sapo.pt] Sent: Thursday, October 25, 2012 7:19 PM To: Rlotus Cc: r-help@r-project.org Subject: Re: [R] How generate random numbers from given vector??? 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@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. ______________________________________________ R-help@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. ______________________________________________ R-help@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.
