Coerce an object of class 'fdClass' or 'imgClass' to class 'rdClass' — as.rdClass • ReMPCA

This function strips the smoothing and grid-related structure from a functional object and converts it to a regular data object of class rdClass.

Usage

as.rdClass(x, Sparsity_parameter = NULL)

Arguments

x: An object of class 'fdClass' or 'imgClass'.
Sparsity_parameter: Optional sparsity parameter to override the original. If NULL, the existing sparsity parameter (if any) is inherited.

Value

An object of class rdClass with smoothing and grid attributes removed, and sparsity parameter preserved or overridden.

Examples

img_object <- imgClass(image = list(matrix(rnorm(100), nr = 50),
                                    matrix(rnorm(100), nr = 50)),
                       argval = NULL,
                       Smoothing_parameter = NULL,
                       Sparsity_parameter = 0)

newrd <- as.rdClass(img_object, Sparsity_parameter = 1:10)
attr(newrd, "Sparsity_parameter")
