R: Calculate the triplet distance between two trees

calcDstTrp {treeman} | R Documentation

## Calculate the triplet distance between two trees

### Description

Returns the triplet distance between two trees.

### Usage

    calcDstTrp(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

The triplet distance is calculated as the sum of different outgroups among every triplet of tips between the two trees. Normalisation is performed by dividing the resulting number by the total number of triplets shared between the two trees. The triplet distance is calculated only for shared tips between the two trees. Parallelizable.
