e2: Get a Contrast Matrix for Type II SS
In sasLM: 'SAS' Linear Model
e2 R Documentation
Get a Contrast Matrix for Type II SS
Description
Makes a contrast matrix for Type II SS.
Usage
e2(x, eps=1e-8)
Arguments
x
an output of ModelMatrix
eps
A value less than this is considered zero.
Details
It makes a contrast matrix for Type II SS. If zapsmall is used, the result becomes less accurate.
Value
A contrast matrix for Type II SS.

Examples
round(e2(ModelMatrix(uptake ~ Plant + Type + Treatment + conc, CO2)), 12)
round(e2(ModelMatrix(uptake ~ Type, CO2)), 12)
round(e2(ModelMatrix(uptake ~ Type - 1, CO2)), 12)
