When fossil = TRUE
, if the tree
contains a tree$root.time
element (for tree's root age), and that order
is set to "past"
, the output ages are adjusted to be starting from the root.time. Else, if no tree$root.time
exists or fossil = FALSE
, tips and nodes age is relative from the tip furthest away from the root. THIS FUNCTION DOES NOT ESTIMATE TREE AGES, it just extracts branch length information and converts it into time units. For basic dating functions in R, check chronos

or use more specialised dating software (e.g. MrBayes, BEAST, RAxML, etc.).
