R: Robust Line Fitting

Robust Line Fitting

line(x, y)

coefficients(tukeyline.obj)
residuals(tukeyline.obj)
fitted.values(tukeyline.obj)
print(tukeyline.obj)

x,y the arguments can be any way of specifying x-y pairs.

This function fits a line robustly as recommended in John Tukey's book Exploratory Data Analysis.

An object of class tukeyline.

Methods are available for the generic functions coefficients, residuals, fitted.values, and print.
