Suppose that I'm working on Hadley's diamond dataset and I want to
review the relationship between price, colour and carat.
I might run the following:
#plot scatter and add some hex binning
main="Variability of Diamond Prices by Carat and Colour")
#facet to get one scatter for each colour, plus overlay a black
coloured loess smoothed line showing the trends in the data
Nice picture, but how do I extract the values of the smoothed line?
Many thanks, dM/
