R: Calculate the BLD between two trees

calcDstBLD {treeman} | R Documentation

## Calculate the BLD between two trees

### Description

Returns the branch length distance between two trees.

### Usage

    calcDstBLD(tree_1, tree_2, nrmlsd = FALSE, parallel = FALSE, progress = "none")

### Arguments

`tree_1` | `TreeMan` object
`tree_2` | `TreeMan` object
`nrmlsd` | Boolean, should returned value be between 0 and 1? Default, FALSE.
`parallel` | logical, make parallel?
`progress` | name of the progress bar to use, see `create_progress_bar`

### Details

BLD is the Robinson-Foulds distance weighted by branch length. Instead of summing the differences in partitions between the two trees, the metric takes the square root of the squared difference in branch lengths. Parallelizable.
