Default Panel Function for densityplot
This is the default panel function for
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
densityfunction. Typically, this should be a list with zero or more of the following components :
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.rugis 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.superposewill 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
subscriptsargument that matches the weights to
plot.points="jitter", the value to use as the
typeargument used to plot points, if requested. This is not expected to be useful, it is available mostly to protect a
typeargument, if specified, from affecting the density curve.
extra graphical parameters. Note that additional arguments to
panel.rugcannot be passed on through
A character string that is prepended to the names of grobs that are created by this panel function.
