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 Lfd
plot(x, axes=NULL, ...)

Value

invisible(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

Side Effects

a plot of the linear differential operator object.
