function constructing additional graphical elements to the plot
...
additional (graphics) parameters which are passed to
the invoked high level plotting function
Details
slider.hist draws a histogram of the data set x by
calling hist and opens a Tcl/Tk widget with one slider.
The slider defines the number of classes of the histogram. Changing the
slider results in redrawing of the plot. For further
details see the help page of hist. rug is used as the
default panel function.
slider.density draws a density trace of the data set x
by plot(density(...)) and opens a Tcl/Tk-widget with two
sliders. The first slider defines the width of the density trace
and the second one the kernel function:
"1-gaussian", "2-epanechnikov", "3-rectangular",
"4-triangular","5-biweight", "6-cosine", "7-optcosine"
Changing one of the sliders results in a redrawing of the plot.
For further details see the help page of density.
rug is used as the default panel function.
