plot

plot a TransferFunction

Description

plot a TransferFunction of dimension 1, 2, or 3.

Usage

## S3 method for class 'TransferFunction'
plot( x, color='red', main=TRUE, add=FALSE, ... )

Arguments

`x`	a `TransferFunction` object with dimension N = 1, 2, or 3.
`color`	Any value acceptable as the `col` argument to `graphics::lines()`. If N=3 this argument is currently ignored.
`main`	If `main=TRUE` then a main title is generated from the object `x`. If `main=FALSE` then no main title is displayed. And if `main` is a character string then that string is used as the main title. If N=3 this argument is currently ignored.
`add`	If `add=TRUE` then the lines are added to an existing plot. If N=3 this argument is currently ignored.
`...`	other graphical parameters, see Details

Details

If N=1 a conventional plot is drawn using graphics::lines(). Commonly used graphical parameters applicable when N=1 are:

`log`	passed on to `plot.default()`. Care must be taken because many transfer functions have 0 in their domains.

If N=2 a grid is generated in the domain box, and the image of that grid is plotted using using graphics::lines().
If N=3 a grid is generated in the domain box, and the image of that grid is plotted in 3D using rgl::lines3d().

Value

TRUE or FALSE
