Re: Exponential Smoothing for ggplot2's stat_smooth()
To use stat_smooth as is, you need a smoothing function that basically
works like lm. So you have two options: to make an interface to
HoltWinters (or find another exponential smooth that already has that
interface) or write your own stat object, which might look something
