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.
