create.constant.basis

Create a Constant Basis

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

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

`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 `x$axes[[1]]` and `x$axes[-1]`. The primary example of this uses `list("axesIntervals", ...)`, e.g., with `Fourier` bases to create `CanadianWeather` plots

a basis object with type component const.

basisobj <- create.constant.basis(c(-1,1))
