Analysis of Two-Way Tables
Overview
Carries out analyses of two-way tables with one observation per cell, together with graphical displays for an additive fit and a diagnostic plot for removable 'non-additivity' via a power transformation of the response. It implements methods from Tukey's Exploratory Data Analysis (1973) <ISBN: 978-0201076165>, including a 1-degree-of-freedom test for row*column 'non-additivity', linear in the row and column effects.
- revised twoway functions to use the names of variables for row/col
- fixed documentation errors/warnings
- include more graphs in examples
- using |> pipes in examples: now depends on R >= 4.1
