margin.plot: Margin Plots of Response for Pairs of Factors

In byandell/pda: Practial Data Analysis for Designed Experiments

Usage

margin.plot(object, ...)
## Default S3 method:
margin.plot(object, response, group, orient = "default", average = "full",
    xlab = xlabs, ylab = ylabs, ...)

Arguments

object	factor whose margins are to be plotted on the horizontal axis. Factor levels are plotted below the marginal means or effects.
response	numeric vector.
group	factor whose levels will be separate traces.
...	optional specification of other parameters to be passed to plotting routines.
orient	"default" = default (as in interaction.plot), "switch" = switch plot orientation of object and group, "both" = plot both ways, "full" = use response, "reduced" = use predicted values from reduced (additive) model.
xlab,ylab	x and y axis labels
average	model to use for marginal averages

Value

a plot will be created showing the requested function of responses for each level of the object at each level of the group. By default, lines for each value of the group are drawn in different styles so that they may be more easily distinguished.

Examples

data( Tukey )
attach( Tukey )
margin.plot( lat, y, geno, orient = "switch", error = "red",
   xlab = "(b) geno marginals by lat", ylab = "",
   xpos = 115, ypos = 100, mod = "")
detach()
