MinMaxMST {cati} | R Documentation |

## Ratio of the shortest distance to the longest distance in a minimum spanning tree

### Description

Ratio of the shortest distance to the longest distance in a minimum spanning tree.

### Usage

```
MinMaxMST(traits, gower.dist = TRUE, scale.tr = TRUE, method.dist = "euclidian")
```

### Arguments

`traits` |
Traits matrix (traits in column) |

`gower.dist` |
Calculate gower distance using the function gowdis from package FD. |

`scale.tr` |
Does traits need to be scale before multi-traits metric calculation? Only use when gower.dist = FALSE. Default is yes. |

`method.dist` |
Method to calculate the distance in case of multi-traits metric (function dist). Only use when gower.dist = FALSE. Default is euclidian. |

### Value

The value of the ratio of the shortest distance to the longest distance in a minimum spanning tree.
