plot.Lfd

Plot a Linear Differential Operator Object

Description

Plot the coefficents of the terms of order 0 through m-1 of an object of class Lfd and length m.

Usage

## S3 method for class 'Lfd'
plot(x, axes=NULL, ...)

Arguments

x

a linear differential operator object to be plotted.

axes

Either a logical or a list or NULL passed to plot.fd.

logical whether axes should be drawn on the plot
list a list used to create custom axes used to 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

...

additional plotting arguments that can be used with function plot

Value

invisible(NULL)

Side Effects

a plot of the linear differential operator object.

Examples

#  Set up the harmonic acceleration operator
dayrange  <- c(0,365)
Lbasis  <- create.constant.basis(dayrange,
                  axes=list("axesIntervals"))
Lcoef   <- matrix(c(0,(2*pi/365)^2,0),1,3)
bfdobj  <- fd(Lcoef,Lbasis)
bwtlist <- fd2list(bfdobj)
harmaccelLfd <- Lfd(3, bwtlist)
plot(harmaccelLfd)
