Default Panel Function for bwplot
Description
This is the default panel function for bwplot
.
Usage
panel.bwplot(x, y, box.ratio = 1,
box.width = box.ratio / (1 + box.ratio),
horizontal = TRUE,
pch, col, alpha, cex,
font, fontfamily, fontface,
fill, varwidth = FALSE,
notch = FALSE, notch.frac = 0.5,
...,
levels.fos,
stats = boxplot.stats,
coef = 1.5,
do.out = TRUE,
identifier = "bwplot")
Arguments
x , y 
numeric vector or factor. Boxplots drawn for each unique value of

box.ratio 
ratio of box thickness to inter box space 
box.width 
thickness of box in absolute units; overrides

horizontal 
logical. If FALSE, the plot is ‘transposed’ in the sense that
the behaviours of x and y are switched. x is now the
‘factor’. Interpretation of other arguments change
accordingly. See documentation of 
pch , col , alpha , cex , font , fontfamily , fontface 
graphical
parameters controlling the dot. 
fill 
color to fill the boxplot 
varwidth 
logical. If TRUE, widths of boxplots are proportional to the number of points used in creating it. 
notch 
if 
notch.frac 
numeric in (0,1). When 
stats 
a function, defaulting to 
coef , do.out 
passed to 
levels.fos 
numeric values corresponding to positions of the factor or shingle variable. For internal use. 
... 
further arguments, ignored. 
identifier 
A character string that is prepended to the names of grobs that are created by this panel function. 
Details
Creates Box and Whisker plot of x
for every level of
y
(or the other way round if horizontal=FALSE
). By
default, the actual boxplot statistics are calculated using
boxplot.stats
. Note that most arguments controlling the
display can be supplied to the highlevel bwplot
call directly.
Although the graphical parameters for the dot representing the median
can be controlled by optional arguments, many others can not. These
parameters are obtained from the relevant settings parameters
("box.rectangle"
for the box, "box.umbrella"
for the
whiskers and "plot.symbol"
for the outliers).
