M: Method to generate hypothesis matrices from formulas

In gmonette/yscs: Collection of tools used in York University's Statistical Consulting Service

Description

Interprets a formula to generate the corresponding portion of a hypothesis matrix. See examples in Lfx. Creates an 'M' object with methods to generate coefficients to estimate interaction terms and comparisons of factor levels.

Usage

M(x, ...)

## S3 method for class 'formula'
M(form, ..., keep.intercept = FALSE)

## S3 method for class 'factor'
M(x, base = NULL)

## S3 method for class 'M'
M(x, ...)

## Default S3 method:
M(x, ...)

## S3 method for class 'M'
e1 * e2

## S3 method for class 'factor'
x < y

## S3 method for class 'factor'
x > y

## S3 method for class 'factor'
x <= y

## S3 method for class 'factor'
x >= y

Arguments

...	other arguments
form	formula
keep.intercept	(default: FALSE) if TRUE generate a column for the intercept term
