This is the default panel function for densityplot.
panel.densityplot(x, darg, plot.points = "jitter", ref = FALSE,
groups = NULL, weights = NULL,
jitter.amount, type, ...,
identifier = "density")
data points for which density is to be estimated
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, give.Rkern, n,
from, to, cut, na.rm (see
density for details)
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 panel.rug is used to plot
a ‘rug’, and "jitter", in which case the points are
jittered vertically to better distinguish overlapping points.
logical, whether to draw x-axis
an optional grouping variable. If present,
panel.superpose will be used instead to display each
subgroup
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.
when plot.points="jitter", the value to use as the
amount argument to jitter.
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.
A character string that is prepended to the names of grobs that are created by this panel function.
