Arguments

fit	A model object for which prediction is desired.
pred	The name of predictor variable
modx	Optional. The name of moderator variable
mod2	Optional. The name of second moderator variable
dep	Optional. The name of dependent variable
xlab	x-axis label.
ylab	y-axis label.
zlab	z-axis label.
width	the width of device
colorn	An integer giving the desired number of intervals. Non-integer values are rounded down.
maxylev	Maximal length of unique values of y axis variable to be treated as a categorical variable.
se	Logical. Whether or not show se. Only effective when the y-axis variable is a categorical one.
show.summary	Logical. Whether or not show statistical summary
overlay	Logical. Whether or not overlay plots
show.error	Logical. Whether or not show error
show.legend	Logical. Whether or not show legend
bg	Character. Background color of plot
type	For the default method, a single character indicating the type of item to plot. Supported types are: 'p' for points, 's' for spheres, 'l' for lines, 'h' for line segments from z = 0, and 'n' for nothing. For the mesh3d method, one of 'shade', 'wire', or 'dots'. Partial matching is used.
radius	The size of sphere
palette	Name of color palette
palette.reverse	Logical. Whether or not reverse the palette order
color	Default color. Color is used when the palette is NULL
show.subtitle	Logical. If true, show regression call as subtitle
show.plane	Logical. If true, show regression plane
plane.color	Name of color of regression plane
plane.alpha	Transparency scale of regression plane
summarymode	An integer indicating method of extracting typical value of variables. If 1, typical() is used.If 2, mean() is used.
...	additional parameters which will be passed to plot3d
