fdaBasis: Use a basis from package fda for univariate representation

In MFPCA: Multivariate Functional Principal Component Analysis for Data Observed on Different Dimensional Domains

Use a basis from package fda for univariate representation

Description

This function allows to use univariate basis representations from the fda package using the funData2fd function from package funData.

Usage

fdaBasis(funDataObject, ...)

Arguments

funDataObject	An object of class funData containing the observed functional data samples and for which the basis representation is to be calculated.
...	Other parameters passed to funData2fd.

Value

scores	The coefficient matrix.
B	A matrix containing the scalar product of all pairs of basis functions. This is NULL, if ortho = TRUE.
ortho	Logical, set to TRUE, if basis functions are orthonormal.
functions	A functional data object containing the basis functions.

Warning

The package fda has be be installed to use this functionality.
