panel.violin {lattice} | R Documentation |
This is a panel function that can create a violin plot. It is
typically used in a high-level call to bwplot
.
panel.violin(x, y, box.ratio = 1, horizontal = TRUE, alpha, border, lty, lwd, col, varwidth = FALSE, bw, adjust, kernel, window, width, n = 50, from, to, cut, na.rm, ...)
x, y |
numeric vector or factor. Violin plots are drawn for each unique
value of y (x ) if horizontal is TRUE
(FALSE )
|
box.ratio |
ratio of height of a violin and inter violin space |
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’. See documentation of bwplot
for a fuller explanation.
|
alpha, border, lty, lwd, col |
graphical parameters controlling the violin. Defaults are taken
from the "bar.fill" settings.
|
varwidth |
logical. If FALSE , the densities are scaled separately for
each group, so that the maximum value of the density reaches the
limit of the allocated space for each violin (as determined by
box.ratio ). If TRUE , densities across violins will
have comparable scale.
|
bw, adjust, kernel, window, width, n, from, to, cut, na.rm |
arguments to density , passed on as appropriate |
... |
arguments passed on to density .
|
Creates Violin plot of x
for every level of y
. Note that
most arguments controlling the display can be supplied to the
high-level (typically bwplot
) call directly.
