eval.basis {fda}R Documentation

Values of Basis Functions or their Derivatives

Description

A set of basis functions are evaluated at a vector of argument values. If a linear differential object is the values are of the result of applying the the operator to each basis function.

Usage

eval.basis(evalarg, basisobj, Lfdobj=0)

Arguments

evalarg a vector of argument values.
basisobj a basis object defining basis functions whose values are to be computed.
Lfdobj either a nonnegative integer or a linear differential. operator object.

Details

Note that if a linear differential operator object is supplied, the basis must be such that the highest order derivative can be computed. If a B-spline basis is used, for example, its order must be one larger than the highest order of derivative required.

Value

a matrix of basis function values with rows corresponding to argument values and columns to basis functions.
