A fast way to get **only** means of successive bins of width k of a
vector z of length nk is:
m <- colMeans(matrix(z,nrow = k))
(you wanted k =50)
This was instantaneous for a length 1e6 numeric vector on my laptop.
However, for anything else, you have to use something like cut() as
others have
Hi Jeffrey,
See ?factor ?rep and ?cut basically you just need to create another
variable that indicates what bin a point belongs to, and then you just
do regular plots. If you want to mix the scatterplot and the binned
points, you'll need to make sure the bins fall somehwere in the same
space.

So you have numeric x and y values.

What is the rule to be applied to form these bins? You may want to
