fdata2fd: 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,
  ...
)

Value

Return an object of the fd class.

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.
