View source: R/sinusoid.R

Description

Plots a sinusoid over 0 to 2π.

Usage

1
sinusoid(amplitude, frequency, phase, ...)

Arguments

amplitude

the amplitude of the sinsuoid (its maximum value).

frequency

the frequency of the sinusoid in 0 to 2π (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,…,2 π, where A is the amplitude, f is the frequency, t is time and P is the phase.
