Interactively detrend a tree-ring series by one of three methods, a
smoothing spline, a linear model, or the mean. This is a wrapper for
detrend.series
.

a number giving the rigidity of the smoothing spline,
defaults to 0.67 of series length if |

a number between 0 and 1 giving the frequency response or wavelength cutoff. Defaults to 0.5. |

This function allows a user to choose a detrending method based on a
plot that is produced by detrend.series
for which it is
essentially a wrapper. The user enters their choice of detrended
method via keyboard at a prompt. See detrend.series
for
examples and details on the detrending methods.
A vector containing the detrended series (y
) according to
the method used with names set to colnames(y)
. These are
typically years. A plot is also produced and the user chooses a method
through keyboard input.
