## Sum of branch length of a classification dendrogram (Petchey and Gaston, 2002)

### Description

Sum of branch length of a classification dendrogram (Petchey and Gaston, 2002)

### Usage

```
SumBL(traits, gower.dist = TRUE, method.hclust = "average",
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. |

`method.hclust` |
Define the method for the hclust function (default is "average" i.e. UPGMA). |

`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 sum of branch length from a classification dendrogram of traits.
