Description Usage Arguments Details Author(s) References Examples

Plots a sinusoid over 0 to 2*π*.

1 |

`amplitude` |
the amplitude of the sinsuoid (its maximum value). |

`frequency` |
the frequency of the sinusoid in 0 to 2 |

`phase` |
the phase of the sinusoid (location of the peak). |

`...` |
additional arguments passed to the plot. |

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.
