R: Default Panel Function for densityplot

F_1_panel.densityplot {lattice} | R Documentation

## 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, ...,
                      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`.
`identifier` | A character string that is prepended to the names of grobs that are created by this panel function.
