In fda.usc: Functional Data Analysis and Utilities for Statistical Computing

Converts fdata class object into fd class object

Description

Converts fdata class object into fd class object using Data2fd function.

Usage

fdata2fd(
  fdataobj,
  type.basis = NULL,
  nbasis = NULL,
  nderiv = 0,
  lambda = NULL,
  ...
)

Arguments

fdataobj	fdata class object.
type.basis	Type of basis. A function create."type.basis".basis must exists. By default, bspline basis is used.
nbasis	Number of basis which is used in create.basis function.
nderiv	Order of derivation which is used in deriv.fd function (optional).
lambda	Weight on the smoothing operator specified by nderiv.
...	Further arguments passed to or from other methods.

Value

Return an object of the fd class.
