From HH v1.8

Percentile

##### Plot all main effects and twoway interactions in a multifactor design

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.

Keywords
aplot, design
##### Usage
panel.interaction2wt(x, y, subscripts, responselab,
trace.values, factor.levels, fun = mean, ...,
key.in=NULL)

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