coocur | R Documentation |

A coocurrence object consists of a matrix with the number of ocurrences in its main diagonal and the number of coocurrences outside this diagonal. Besides, this object has two attributes: 1) n is the total of the sum of the ocurrences in each row.2) m is the sum of the maximum number of ocurrences in each row.

```
coocur(ocurrences, minimum = 1, maximum = Inf,
sort = FALSE, decreasing = TRUE)
```

`ocurrences` |
an ocurrence matrix or data frame |

`minimum` |
minimum frequency to be considered |

`maximum` |
maximum frequency to be considered |

`sort` |
sort the coincidence matrix according to frequency of events |

`decreasing` |
decreasing or increasing sort of the matrix |

Produce a matrix of coocurrences from a matrix of occurences.

An object of `cooc`

class with a coocurrence matrix. It has two attributes:

`n` |
Total sum of occurences) |

`m` |
Sum of maximum occurences in each row of the ocurrence matrix |
