datelife is an R package that allows researchers and the general audience to obtain open scientific data on the age of any organism they are interested in.
datelife retrieves organism ages from a database of dated phylogenetic trees (chronograms), which have been peer-reviewed and published in association with a scientific research article in an indexed journal (Open Tree of Life’s tree store). As such, these organism ages constitute state-of-the-art, peer-reviewed, public scientific knowledge, that can be accessed and reused by experts and non-experts in the field alike.
