Hello,
Just run your code and every time there's an error correct it.
number <- c(0,1,3,4,5,6,8)
rsidp <- function(x){
y <- sample(number,x,replace=TRUE)
y # don't need return()
}
plot(0, xlim=c(0,20), ylim=c(0,20), type="n", xlab="Sample
size",
ylab="Sample variance")
for (i in seq(1:20)){
retVal=rsidp(i)
points (i, var(retVal),pch=i,col=i)
}
Hope this helps,
Rui Barradas
