Usage
panel.densityplot(x, darg, plot.points = "jitter", ref = FALSE,
groups = NULL, weights = NULL,
jitter.amount, type, ...)Arguments
x
data points for which density is to be estimated
darg
list of arguments to be passed to the density
function. Typically, this should be a list with zero or more of the
following components : bw, adjust, kernel,
window, width
plot.points
logical specifying whether or not the data points should be plotted
along with the estimated density. Alternatively, a character string
specifying how the points should be plotted. Meaningful values are
"rug", in which case
ref
logical, whether to draw x-axis
groups
an optional grouping variable. If present,
panel.superpose will be used instead to display each
subgroup weights
numeric vector of weights for the density
calculations. If this is specified, the ... part must
also include a subscripts argument that matches the weights
to x.
jitter.amount
when plot.points="jitter", the value to use as the
amount argument to jitter. type
type argument used to plot points, if requested.
This is not expected to be useful, it is available mostly to protect
a type argument, if specified, from affecting the density
curve.
...
extra graphical parameters. Note that additional
arguments to panel.rug cannot be passed on through
panel.densityplot.
