Details

slider.lowess.plot computes a scatterplot of the data. Then a LOWESS smoother line is added to the plot. For more details about the lowess parameters f and iter take a look at the help page of lowess. The parameters are set by moving sliders of the control widget. The first slider defines the smoother span f and the second one the number of iterations.
