If that's the right diagnosis:

ok, now I got it. You want some kind of running-mean.
The function -lowess- has an option to create a new
variable that is a running mean.
BUT, this is not exactly what we want here, because this
mean is calculated at the center of the running window.
We want the mean at the right end of the window.
