## Dominant Frequencies in Multiple (Genetic) Time Series

### Description

`dominant.freqs`

returns the m dominant frequencies (highest peaks)
in each of the periodogram computed for the individual time series.

### Usage

dominant.freqs(x, m=1, ...)

### Arguments

`x` |
multivariate (genetic) time series (=matrix where each column
corresponds to one time series), or a vector with a single
time series |

`m` |
number of dominant frequences |

`...` |
arguments passed to `periodogram` |

### Value

A matrix (or vector, if only 1 time series is considered) with the
dominant frequencies. In a matrix, each column
corresponds to one time series.
