Description Usage Arguments Value References Examples

This is a wrapper that computes the periodogram

1 | ```
periodogram(y,log='no',plot=TRUE,ylab="Periodogram", xlab="Frequency",lwd=2,...)
``` |

`y` |
A univariate time series |

`log` |
if set to "yes", the periodogram is plotted on the log-scale; default="no" |

`plot` |
The periodogram is plotted if it is set to be TRUE which is the default |

`ylab` |
label on the y-axis |

`xlab` |
label on the x-axis |

`lwd` |
thickness of the periodogram lines |

`...` |
other arguments to be passed to the plot function |

A list that contains the following elements:

`freq` |
Vector of frequencies at which the spectral density is estimated. (Possibly approximate Fourier frequencies. |

`spec` |
Vector of estimates of the periodogram at frequencies corresponding to freq. |
