boxplotlegend: 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

Value

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

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.
