Polynomial regression line
I would think you could also do so with lines() directly, though you'll have to choose an appropriate mesh of points to do so. A little wrapper function could be written to do so pretty easily if you want to combine it with the scatterplot, but since the fitted values are already in the output of lm something like this should work: # Untested lines(m$x, m$fitted.values) Michael

The cubic regression of my model is significant and I want to plot a line that best fits. It's not abline() function, because it has a curve. Please, how can I plot it?
Will curve() do it for you? ?curve Cheers, Ben
