View source: R/BioGeoBEARS_stratified_v1.R

This function chops a tree like a hedge-trimmer, cutting straight across at a particular timepoint. The pieces are returned, as is the leftover tree, with branches shortened appropriately. Pieces that are mini-trees are returned as ape objects, whereas single branches are just lengths.

1	chainsaw2(tr, timepoint = 10, return_pieces = TRUE)

`tr`	An ape phylo object.
`timepoint`	The time at which the tree should be "chopped".
`return_pieces`	Default TRUE, which means pieces should be returned

This function is used during stratification, but could have other uses as well.

chainsaw_result (a list object with the pieces) or tree_to_chainsaw, just the leftover tree

Go BEARS!
