adegraphics (version 1.0-22)

addtext: Adds labels on graphics.

Description

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

Usage

addtext(object, xcoord, ycoord, label, plot = TRUE, ...)

Value

An object of class ADEgS.

Arguments

object

an object of class ADEg, trellis or ADEgS

xcoord

an integer (or a vector) indicating where label is(are) plotted on the x-axis, passed to the adeg.panel.label

ycoord

an integer (or a vector) indicating where label is(are) plotted on the y-axis, passed to the adeg.panel.label

label

a character string (or a vector) containing the label(s) displayed on object

plot

a logical indicating if the graphics is displayed

...

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