binary_to_table {AnthropMMD} | R Documentation |

## Converts a data frame of binary (i.e., presence/absence) trait information into a table of sample sizes and frequencies.

### Description

This function allows to get a summary of sample sizes and frequencies
for each trait in each group. It is also mandatory to apply this
function before using the `mmd`

function, since the latter
only accepts table of frequencies, and cannot work with raw binary data.

### Usage

```
binary_to_table(data, relative = FALSE)
```

### Arguments

`data` |
A binary (0/1 for presence/absence of traits) data frame
with |

`relative` |
Boolean. Indicates if the last rows of the table must contain frequencies (i.e., number of individuals having a given trait) or relative frequencies (i.e., proportions). |

### Value

A matrix with `2*K`

rows (`K`

being the number of groups in
the dataset) and `p`

columns (one per trait).
The first `K`

rows are the sample sizes, the last `K`

rows are
trait frequencies.
