i.detrend.series | R Documentation |

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)
```

`y` |
a |

`y.name` |
an optional |

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

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

`pos.slope` |
a |

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 (

) according to
the method used with names set to `y``colnames(`

. These are
typically years. A plot is also produced and the user chooses a method
through keyboard input.
