panel.densityplot: Default Panel Function for densityplot

In lattice: Trellis Graphics for R

Default Panel Function for densityplot

Description

This is the default panel function for densityplot.

Usage

panel.densityplot(x, darg, plot.points = "jitter",
                  ref = FALSE,
                  groups = NULL,
                  weights = NULL,
                  jitter.amount,
                  type, ...,
                  grid = lattice.getOption("default.args")$grid,
                  identifier = "density")

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, give.Rkern, n, from, to, cut, na.rm (see density for details)
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 panel.rug is used to plot a ‘rug’, and "jitter", in which case the points are jittered vertically to better distinguish overlapping points.
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.
grid	A logical flag, character string, or list specifying whether and how a background grid should be drawn. In its general form, grid can be a list of arguments to be supplied to panel.grid, which is called with those arguments. Three shortcuts are available: TRUE: roughly equivalent to list(h = -1, v = -1) "h": roughly equivalent to list(h = -1, v = 0) "v": roughly equivalent to list(h = 0, v = -1) No grid is drawn if grid = FALSE.
identifier	A character string that is prepended to the names of grobs that are created by this panel function.
