Accessing Linear Model Fits
Description
All these functions are methods for class "lm" objects.
Usage
## S3 method for class 'lm'
coefficients(object, ...) ; Arguments
object, x |
an object of class |
... |
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))
