sinusoid: Plot a Sinusoid

In season: Seasonal Analysis of Health Data

Plot a Sinusoid

Description

Plots a sinusoid over 0 to 2\pi.

Usage

sinusoid(amplitude, frequency, phase, ...)

Arguments

amplitude	the amplitude of the sinusoid (its maximum value).
frequency	the frequency of the sinusoid in 0 to 2\pi (number of cycles).
phase	the phase of the sinusoid (location of the peak).
...	additional arguments passed to the plot.

Details

Sinusoidal curves are useful for modelling seasonal data. A sinusoid is plotted using the equation: A\cos(ft-P), t=0,\ldots,2 \pi, where A is the amplitude, f is the frequency, t is time and P is the phase.
