Topological order — topological

Compute the topological order of a tree

topological_order(MTG, ascend = FALSE)

Arguments

MTG	An MTG tree as from `read_mtg()`
ascend	Is the order computed from the base (`TRUE`), or the tip (`FALSE`) ?

Value

Nothing, update the values of the MTG in-place. The MTG is enriched with the topological order of each node

Examples

filepath= system.file("extdata", "simple_plant.mtg", package = "XploRer")
MTG= read_mtg(filepath)
