Coerce an object of class 'rdClass', 'fdClass', or 'imgClass' to class 'hdClass'

This function wraps a single regular or functional object into a hybrid data object.

Usage

as.hdClass(
  x,
  Smoothing_parameter = NULL,
  Sparsity_parameter = NULL,
  argval = NULL
)

Arguments

x

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

Smoothing_parameter

Optional smoothing parameter for the row direction. If NULL, taken from input attributes or defaulted in hdClass().

Sparsity_parameter

Optional sparsity parameter for the row direction. If NULL, taken from input attributes or defaulted in hdClass().

argval

Optional grid points for rows. If NULL, taken from input attributes or defaulted.

Value

An object of class 'hdClass'.

Details

This function returns a modified version of the input object as an hdClass object. Due to R's copy-on-modify semantics for S3 objects, users must reassign the result to retain changes. For example: x <- as.hdClass(x).

Examples

fd_obj <- fdClass(matrix(rnorm(100), 10, 10))
hd_obj <- as.hdClass(fd_obj, Sparsity_parameter = 0:5)
attr(hd_obj, "Sparsity_parameter")
#> [1] 0 1 2 3 4 5
