panel.densityplot(x, y, cut, from, to, n = 50, type = "l",
width, window = "gaussian", ...)
ARGUMENTS:
x
vector of observations from distribution whose density is to
be estimated.
y
dummy variable.
cut
fraction of
width for controlling default values of
from and
to.
For gaussian windows,
cut=.75; otherwise,
cut=.5 .
from,to
the n estimated values of density are equally spaced between
from and
to. Default is range of data extended by
width*cut.
n
the number of equally spaced points at which to estimate density.
type
character string telling how to plot the
x and
y values:
"p" for using the
points function,
"l" for using the
lines function.
width
width of the window. Default is width of histogram bar which is
determined by
log(length(x), base=2)+1 bars to cover
the range of
x. The standard error of a Gaussian window is
width /4.
window
character string giving the type of window used in
computation
"cosine",
"gaussian" ,
"rectangular" ,
"triangular"
(one character is sufficient).
...
graphical parameters that are passed to
points or
lines.
By default, the trellis parameter list
plot.symbol will be used to control
character size (
cex ), plotting symbol (
pch ), font, and color (
col )
for points; the
plot.line parameters will be used to control
line width (
lwd ), line type (
lty ), and color (
col ) for lines.
