panel.interaction2wt {HH}R Documentation

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,
                     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, ...)

Arguments

panel.interaction2wt arguments:

x levels of x-factor
y Summary value of response variable at each level of x- and trace-factors.
subscripts used to get the right set of response values for the summary statistics on the off-diagonals
responselab Character name of response variable, defaults to the name of the response variable.
trace.values levels of trace-factor
fun Summary function, defaults to mean
se standard errors to be passed to panel.intxplot. se Missing, logical, or a numeric vector. If missing or FALSE, standard errors are not plotted. If TRUE, the standard errors are calculated from the sufficient statistics for each group as the groups standard deviation divided by the square root of the group observation count. If a numeric vector, it is evaluated in the environment of the sufficient statistics.
box.ratio passed to panel.bwplot.intermediate.hh
... extra arguments, primarily color, to be passed to panel.bwplot.intermediate.hh
key.in arguments to be passed through to the key for the trace-factor in each row of the display.
factor.position "position" attribute of factor.
simple logical. TRUE if simple effects are to be displayed.
simple.offset, simple.scale named list of offset and scale for the response and trace factors. See interaction.positioned for their use.
data.x data.frame containing factors from the input data.frame
col.by.row logical. If TRUE (the default), simple effects plots color the simple effects on the main diagonals in the same color as the trace levels in their row. If FALSE, then simple effects are colored to match the x levels in their column.
which.given, which.panel, var.name, factor.levels, shingle.intervals see documentation for strip.default
strip.names Force strip.names=TRUE
style force style=1
