panel.superpose: Panel Function for Display Marked by groups

Description

This is an useful panel function for trellis displays. Uses a grouping variable, plotting the x and y variables with different graphical properties for each distinct value of the grouping variable.

Usage

panel.superpose(x, y, subscripts, groups, type="p", ...)

Arguments

x,y
coordinates of the points to be displayed
subscripts
subscripts giving indices in original data frame
groups
a grouping variable. Different graphical parameters will be used for each distinct value of groups. The default graphical parameters are obtained from superpose.symbol and superpose.line using
type
if "p" points are plotted, if "l", the points are joined by lines, if "b", both are done.

synopsisi

panel.superpose(x, y, subscripts, groups, type = "p", col = superpose.symbol$col, pch = superpose.symbol$pch, lty = superpose.line$lty, ...)
