Usage
panel.barchart(x, y, box.ratio = 1,
horizontal = TRUE,
origin = NULL, reference = TRUE,
stack = FALSE,
groups = NULL,
col = if (is.null(groups)) bar.fill$col else superpose.fill$col,
border = if (is.null(groups)) bar.fill$border else superpose.fill$border,
lty = if (is.null(groups)) bar.fill$lty else superpose.fill$lty,
lwd = if (is.null(groups)) bar.fill$lwd else superpose.fill$lwd,
...)Arguments
x
Extent of Bars. By default, bars start at left of panel,
unless origin is specified, in which case they start there
y
Horizontal location of bars, possibly factor
box.ratio
ratio of bar width to inter-bar 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'. Interpretation of other arguments change
accordingly. See documentation of bwplot for a fuller
expla
origin
origin of the bars. For grouped displays with
stack = TRUE, this argument is ignored and the origin set to
0. Otherwise, defaults to NULL, in which case bars start at
leftmost end of panel.
reference
logical, whether a reference line is to be drawn at
the origin
stack
logical, relevant when groups is non-null. If
FALSE (the default), bars for different values of the
grouping variable are drawn side by side, otherwise they are
stacked.
groups
optional grouping variable
...
extra arguments will be accepted but ignored
