adegraphics (version 1.0-4)

adeg.panel.label: Panel function for adding labels.

Description

Panel function for drawing labels into a trellis graphic (lattice package) with or without boxes around labels.

Usage

adeg.panel.label(x, y, labels, plabels, pos = NULL)

Arguments

x

a numeric vector, x-coordinates for the labels

y

a numeric vector, y-coordinates for the labels

labels

a vector of character string, the labels

plabels

a list of parameters as an extract of adegpar("plabels"), used for labels' drawing. Each value can be a vector and will be recycled if necessary:

• alpha,cex,col: drawing parameters for th

Value

• Draws the labels.

References

The algorithm used for labels positions optimization is inspired by the pointLabel function of the maptools package developed by Tom Short.
