panel.interaction2wt: Plot all main effects and twoway interactions in a multifactor design

Description

This is the panel function for interaction2wt. The main diagonal displays boxplots for the main effects of each factor. The off-diagonals show the interaction plots for each pair of factors. The i,j panel shows the same factors as the j,i but with the trace- and x-factor roles interchanged.

Usage

panel.interaction2wt(x, y, subscripts,
                     responselab, trace.values,
                     factor.levels, factor.position,
                     fun = mean,
                     se,
                     ...,
                     box.ratio,
                     simple=FALSE,
                     simple.offset,
                     simple.scale,
                     simple.pch,
                     data.x,
                     col.by.row=TRUE,
                     key.in=NULL)

strip.interaction2wt(which.given, which.panel, var.name,
                     factor.levels, shingle.intervals,
                     strip.names = c(TRUE, TRUE), style = 1, ...)
