Boxplotlegend

Description

This function plots the legend in form of a boxplot. The symbols represent the different levels (e.g. whiskers, median, ...) of the boxplot.

Usage

boxplotlegend(X, Y, el, boxinfo, x.shift = 40000, xf = 10000, y.shift = 0.2,
y.scale = 130000, legend.title = "Legend", cex.legtit = 1, logscale = TRUE,
symb = c(1, 1, 16, 3, 3), ssize = c(1.5, 1, 0.3, 1, 1.5), accentuate = FALSE,
cex.scale = 0.8)

Arguments

X	X-coordinates
Y	Y-coordinates
el	variable considered
boxinfo	from boxplot(el) or boxplotlog(el)
x.shift	shift in x-direction
xf	width in x-direction
y.shift	shift in y-direction (from title)
y.scale	scale in y-direction
legend.title	title for legend
cex.legtit	cex of title for legend
logscale	if TRUE plot boxplot in log-scale
symb	symbols to be used (length 5!)
ssize	symbol sizes to be used (length 5!)
accentuate	if FALSE no symbols for the upper values (e.g. upper "hinge", upper whisker) are assigned
cex.scale	cex for text "log-scale" for scale

Details

Takes the information provided by the argument boxinfo and plots a boxplot corresponding to the values. If there are no upper or/and lower outliers the symbols for the upper or/and lower whiskers will be ignored.

Value

Plots the legend with respect to the boxplot and returns the symbols, size and the quantiles used for the legend.
