In hankOlofs/linreg: Fitting Linear Regression Models

Description Usage Arguments Value References Examples

The function linreg takes a formula object and a data.frame as arguments, and returns an object as an S3 class. It performs ordinary least squares or QR decomposition to calculate different statistics.

1	linreg(formula, data, QR = FALSE)

`formula`	a formula, like y~x
`data`	a data frame
`QR`	use QR decomposition if TRUE, else OLS

A linreg class object
