function (the mean by default) of the
response for the combinations of the three
factors specified as the
x.factor (plotted on the x axis of each plot), the
groups.factor (plotted as separate lines in each plot) and the
levels are plotted in different plots). Interaction plots for more than three
factors can be produced by using
fac.combine to combine all but two of them into a single
factor that is specified as the
interaction.ABC.plot(response, x.factor, groups.factor, trace.factor,data, fun="mean", title="A:B:C Interaction Plot", xlab, ylab, key.title, lwd=4, columns=2, ...)
