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.
i.detrend.series(y, y.name = NULL, nyrs = NULL, f = 0.5,
pos.slope = FALSE)a numeric vector. Usually a tree-ring series.
an optional character vector to name the series
for plotting purposes.
a number giving the rigidity of the smoothing spline,
defaults to 0.67 of series length if nyrs is
NULL.
a number between 0 and 1 giving the frequency response or wavelength cutoff. Defaults to 0.5.
a logical flag. Will allow for a positive
slope to be used in method "ModNegExp". If FALSE the
line will be horizontal.
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.
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.
