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.
