In Table D-1, functions that smooth data are given. Most of the smoothers do not automatically plot the smoothed data, which can be plotted with a call to plot() (or with lines() or points() after a call to plot()).

Table D-1

Functions for smoothing data

Function Name	Description
kernel( )	For a one-element character vector or a numeric vector (coef).  The possible character strings (preset kernels) for coef are “daniell”, “dirichlet”, “fejer”, or “modified.daniell”.  The function gives the design of the kernel to use with smoothers that use a kernel.  Returns an object of class tskernel.  Can be plotted ...
