create.constant.basis: Create a Constant Basis

Description

Create a constant basis object, defining a single basis function whose value is everywhere 1.0.

Usage

create.constant.basis(rangeval=c(0, 1), names="const", axes=NULL)

Arguments

rangeval

a vector of length 2 containing the initial and final values of argument t defining the interval over which the functional data object can be evaluated. However, this is seldom used since the value of the basis function does not depend on the range or any argument values.

names

a character vector of length 1.

axes

an optional list used by selected plot functions to create custom axes. If this axes argument is not NULL, functions plot.basisfd, plot.fd, plot.fdSmooth plotfit.fd, plotfit.fdSmooth, and plot.Lfd will create axes via do.call(x$axes[[1]], x$axes[-1]). The primary example of this uses list("axesIntervals", ...), e.g., with Fourier bases to create CanadianWeather plots

Value

a basis object with type component const.
