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.
