phasor: Plot Phasors

In phonTools: Tools for Phonetic and Acoustic Analyses

Description

Plot phasors representing one or more complex-valued variables.

Usage

phasor (num, scaled = TRUE, add = FALSE, circle = FALSE, 
        xlim, ylim, ...)

Arguments

num	A complex-valued variable to be plotted as a phasor, or a vector of such variables.
scaled	If TRUE, phasor magnitudes are scaled to 1.
add	If TRUE, phasors are plotted on existing figure. If FALSE, a new plot is created.
circle	If TRUE and scaled is TRUE, the unit circle is drawn.
xlim	x-axis range.
ylim	y-axis range.
...	Additional arguments are passed to the internal call of 'plot' and 'arrows'.

Details

Complex-valued variables may be created using the complex() function.
