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)

Value

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

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.
