Converts fdata class object into fd class object

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.
