Adds points on graphics.

Adds a trellis object containing one or several points on one or several graphical objects.

Usage

addpoint(object, xcoord, ycoord, plot = TRUE, ...)

Arguments

object

an object of class ADEg or ADEgS

xcoord

an integer (or a vector) indicating where label is(are) plotted on the x-axis, passed to the panel.points function of the lattice package

ycoord

an integer (or a vector) indicating where label is(are) plotted on the y-axis, passed to the panel.points function of the lattice package

plot

a logical indicating if the graphics is displayed

...

Other arguments. Additional graphical parameters (see the ppoints list in adegpar and trellis.par.get). If object is an ADEgS, the argument which identify which ADEg is/are used for superposition.

Value

An object of class "ADEgS".
