Change (basis) representation of a tf-object

Source: R/rebase.R
tf_rebase.Rd

Apply the representation of one tf-object to another; i.e. re-express it in the other's basis, on its grid, etc.
Useful for making different functional data objects compatible so they can be combined, compared or computed with.

Usage

tf_rebase(object, basis_from, arg = tf_arg(basis_from), ...)

# S3 method for tfd
tf_rebase(object, basis_from, arg = tf_arg(basis_from), ...)

# S3 method for tfb
tf_rebase(object, basis_from, arg = tf_arg(basis_from), ...)

Arguments

object

a tf object whose representation should be changed

basis_from

the tf object with the desired basis, arg, evaluator, etc.

arg

optional new arg values, defaults to those of basis_from

...

forwarded to the tfb or tfd constructors

Value

a tf-vector containing the data of object in the same representation as basis_from (potentially modified by the arguments given in ...).

Details

This uses double dispatch (S3) internally, so the methods defined below are themselves generics for methods tf_rebase.tfd.tfd, tf_rebase.tfd.tfb_spline, tf_rebase.tfd.tfb_fpc, tf_rebase.tfb.tfd, tf_rebase.tfb.tfb that dispatch on object_from.

Methods (by class)

  • tf_rebase(tfd): re-express a tfd-vector in the same representation as some other tf-vector

  • tf_rebase(tfb): re-express a tfb-vector in the same representation as some other tf-vector.
