calcDstMtrx: Calculate the distance matrix

Description

Returns a distance matrix for specified ids of a tree.

Usage

calcDstMtrx(tree, ids, parallel = FALSE, progress = "none")

Arguments

tree

TreeMan object

ids

IDs of nodes/tips

parallel

logical, make parallel?

progress

name of the progress bar to use, see create_progress_bar

Details

The distance between every id in the tree is calculated by summing the lengths of the branches that connect them. This can be useful for testing the distances between trees, checking for evoltuionary isolated tips etc. Parallelizable.

Examples

# NOT RUN {
# checking the distance between two trees
library(treeman)
tree_1 <- randTree(10)
tree_2 <- randTree(10)
dmat1 <- calcDstMtrx(tree_1, tree_1['tips'])
dmat2 <- calcDstMtrx(tree_2, tree_2['tips'])
mdl <- cor.test(x=dmat1, y=dmat2)
as.numeric(1 - mdl$estimate)  # 1 - Pearson's r
# }
