Hello,
You had enough answers to variants of this question to already know to
open a graphics device once and _just_ once using plot() and then, in
the loop, use points().
plot(1, type = "n", xlim = c(0, 20), ylim = c(0, 8),
ylab="sample mean", xlab="sample size")
for (i in seq(1:20)){
rsidpVector=rsidp(i)
mean(rsidpVector)
points(length(rsidpVector), mean(rsidpVector))
}
And what's wrong with your "new" function rsidp()? What is i+0 supposed
to do?
Hope this helps,

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)
}
