Set Smoothness Tuning Parameter

Assigns a smoothing tuning parameter to an object of class rdClass, fdClass, imgClass, or hdClass.

Usage

setSmoothnessParameter(obj, Smoothing_parameter)

Arguments

obj

An object of class rdClass, fdClass, imgClass, or hdClass.

Smoothing_parameter

A numeric value or vector representing the smoothing parameter(s) to assign to the object.

Value

The modified object with updated Smoothing_parameter attribute.

Details

This function updates the "Smoothing_parameter" attribute of the given object. Since R uses copy-on-modify semantics for S3 objects, users must reassign the object after calling this function:

  obj <- setSmoothnessParameter(obj, c(0.01, 0.1, 1))

Without reassignment, the original object remains unchanged.

Examples

fd_obj <- fdClass(matrix(rnorm(100), 10, 10))
fd_obj <- setSmoothnessParameter(fd_obj, c(0.01, 0.1, 1))
attr(fd_obj, "Smoothing_parameter")
#> [1] 0.01 0.10 1.00
