panel.densityplot {lattice}R Documentation

Default Panel Function for densityplot


This is the default panel function for densityplot.


panel.densityplot(x, darg, plot.points = "jitter", ref = FALSE,
                  groups = NULL, 
                  jitter.amount, type, ...)


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
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
