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

This function allows a user to choose detrending curves based on plots
that are produced by detrend.series
for which it is
essentially a wrapper. The user enters their choice of detrended
method via keyboard at a prompt for each ring width series in
rwl
. See detrend.series
for examples and
details on the detrending methods.
A data.frame
containing each detrended series according to the
method used as columns and rownames set to
colnames(y)
. These are typically years. Plots are also
produced as the user chooses the detrending methods through keyboard
input.
