In lm.beta: Add Standardized Regression Coefficients to Linear-Model-Objects

Print Coefficients of Standardized Linear-Model-Object

Description

S3-method coef for object lm.beta.

Usage

## S3 method for class 'lm.beta'
coef(object, standardized = TRUE, ...)

Arguments

object	An R object of class lm.beta
standardized	Logical. Should the standardized values be returned?
...	additional arguments. (Currently ignored.)
