Coerce an object of class 'rdClass' or 'imgClass' to class 'fdClass'.

Usage

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

Arguments

x: An object of class 'rdClass' or 'imgClass'.
Sparsity_parameter: Optional sparsity parameter to assign. If NULL, defaults are used.
Smoothing_parameter: Optional smoothing parameter to assign. If NULL, defaults are used.
argval: Optional vector of grid points for columns. If NULL, defaults are used.

Value

An object of class 'fdClass' with user-specified or inherited regularization parameters.

Examples

img_object <- imgClass(
  image = list(matrix(rnorm(100), nrow = 10), matrix(rnorm(100), nrow = 10)),
  argval = NULL,
  Smoothing_parameter = NULL,
  Sparsity_parameter = 0
)
newfd <- as.fdClass(img_object)
