make_legend: Add a color-scale legend to a plot

Description

This function adds a nicely formatted color-scale legend to a plot. NOTE: This function will be made available in the LICORS package in the next release. It will then be removed from the NAMESPACE of the LSC package.

Usage

make_legend(data = NULL, col = NULL, side = 1, zlim = NULL, col.ticks = NULL, 
    cex.axis = 2, max.height = 1, col.label = "")

Arguments

data

data for which the legend should be plotted

side

on which side of the plot (1=bottom, 2=left, 3=top, 4=right)

col.ticks

color tick marks

max.height

height of the density plot (typically not modified by user)

cex.axis

The magnification to be used for axis annotation relative to the current setting of cex.

col

colors: either a string decribing a pallette from the RColorBrewer package (see also http://colorbrewer2.org/), or a list of colors (see image for suggestions).

zlim

minimum and maximum z values for which colors should be plotted, defaulting to the range of the finite values of data.

col.label

same as zlim.label

Examples

xx <- rnorm(100)
make_legend(xx, col = "RdBu")
make_legend(xx, col = "RdYlGn", side = 4)
