search for: rsidp

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 m...

Plz help me ;(( I lost 7 hours for thinking and doing this code ;( I need to create points.....20 points(dots). All these dots have to be in one graph... when i run this code....it gives me only one dote..... number<- (0,2,3,4,5,6,8) for (i in seq(1:20)) {rsidpVector=rsidp(i) mean(rsidpVector) plot (length(rsidpVector), mean(rsidpVector), ylab="sample mean", xlab= "sample size") } rsidp<- function(x){ i+0 {y<-sample(number,x,replace = TRUE)} return(y) } -- View this message in context: http://r.789695.n4.nabble.com/wanna-crea...
