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)
Arguments
x, y
numeric vector or factor. Boxplots drawn for each unique value of
y
(x
) if horizontal
is TRUE
(FALSE
)
box.ratio
ratio of box thickness to inter box space
box.width
thickness of box in absolute units; overrides
box.ratio
. Useful for specifying thickness when the
categorical variable is not a factor, as use of box.ratio
alone cannot achieve a thickness greater than 1.
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. pch="|"
is treated
specially, by replacing the dot with a line (similar to
boxplot
) 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
is TRUE
, a notch is drawn in each
side of the boxes. If the notches of two plots do not overlap this
is strong evidence that the two medians differ (Chambers et
al., 1983, p. 62). See
notch.frac
numeric in (0,1). When notch=TRUE
, the
fraction of the box width that the notches should use.
stats
a function, defaulting to boxplot.stats
,
that accepts a numeric vector and returns a list similar to the
return value of boxplot.stats
. The function must accept
arguments coef, do.out
passed to stats
levels.fos
numeric values corresponding to positions of the
factor or shingle variable. For internal use.
...
further arguments, ignored.
