You'll need to apply the smoothing function to the data separately, store that
and plot the curve (?) fom that.
You can plot a line for many model fits using the associated predict() method
and if necessary specifying a newdata data frame containing neatly-spaced
predictors; look up the generic ?predict and predict.lm for a typical case.
predict.nlm and predict.loess also exist and work much the same way.
