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.
