You got twenty dots. It's just that they were on twenty separate plots.

That line above is not valid R code. You should have gotten an error

You should define a function before it is called. It was only because I
corrected the error in the assignment to "number" and ran it again that the
function was available ... for plotting twenty separate points in twenty
separate plots.
number<- c(0,2,3,4,5,6,8)
rsidp<- function(x){
i+0 # that line does nothing
{y<-sample(number,x,replace = TRUE)}
return(y) # that line only wastes time
}
plot(NA, xlim=c(1,20), ylim=range(number), ylab="sample mean", xlab=
"sample size")
for (i in seq(1:20))
{rsidpVector=rsidp(i)
mean(rsidpVector) # that line does nothing
points (length(rsidpVector), mean(rsidpVector) )
}
