toolTimeSpline: Smooth a magclass time series with optional anchor years

In madrat: May All Data be Reproducible and Transparent (MADRaT) *

Smooth a magclass time series with optional anchor years

Description

Smooths a magclass time series using spline approximation with the given degrees of freedom. Optionally, specific years can be "pegged" (anchored) to stay close to their original values during smoothing. Anchoring is enforced by applying high weights to those years.

Usage

toolTimeSpline(x, dof = 5, peggedYears = NULL, anchorFactor = 10)

Arguments

x	A magclass object.
dof	Degrees-of-freedom per 100 years (higher -> more degrees of freedom, less smoothing; default 5).
peggedYears	Integer vector of years (e.g. 'c(2020, 2050, 2100)') to anchor during smoothing; NULL for none (default).
anchorFactor	Numeric multiplier for anchor weights (default 10); larger values more strongly enforce pegging.

Value

A magclass object of the same shape, with each time series spline-smoothed.
