 plot.Lfd R Documentation

## 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`

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)
