Accessing Linear Model Fits

Description

All these functions are methods for class "lm" objects.

Usage

coefficients(object, ...) ; \method

Arguments

object, x an object of class lm, usually, a result of a call to lm.
... further arguments passed to or from other methods.

Details

The generic accessor functions coefficients, effects, fitted.values and residuals can be used to extract various useful features of the value returned by lm.

Examples


##-- Continuing the  lm(.) example:
coef(lm.D90)# the bare coefficients

## The 2 basic regression diagnostic plots [plot.lm(.) is preferred]
plot(resid(lm.D90), fitted(lm.D90))# Tukey-Anscombe's
abline(h=0, lty=2, col = 'gray')

qqnorm(residuals(lm.D90))
