use_calibrations_bladj

The function <code>use_calibrations_bladj</code> prepares the input for BLADJ
and calls <code>make_bladj_tree()</code>.

Methods and workflows to get chronograms (i.e., phylogenetic trees with branch lengths
proportional to time), using open, peer-reviewed, state-of-the-art scientific data on time of lineage divergence.
This package constitutes the main underlying code of the DateLife web service
at <https://www.datelife.org>. To obtain a single summary chronogram from a group of
relevant chronograms, we implement the Super Distance Matrix (SDM) method
described in Criscuolo et al. (2006) <doi:10.1080/10635150600969872>.
To find the grove of chronograms with a sufficiently overlapping set of taxa
for summarizing, we implement theorem 1.1. from Ané et al. (2009)
<doi:10.1007/s00026-009-0017-x>.
A given phylogenetic tree can be dated using time of lineage divergence data
as secondary calibrations (with caution, see Schenk (2016) <doi:10.1371/journal.pone.0148228>).
To obtain and apply secondary calibrations, the package implements the congruification method described
in Eastman et al. (2013) <doi:10.1111/2041-210X.12051>. Tree dating can be performed with different methods
including BLADJ (Webb et al. (2008) <doi:10.1093/bioinformatics/btn358>), PATHd8
(Britton et al. (2007) <doi:10.1080/10635150701613783>), mrBayes (Huelsenbeck
and Ronquist (2001) <doi:10.1093/bioinformatics/17.8.754>), and treePL (Smith
and O'Meara (2012) <doi:10.1093/bioinformatics/bts492>).

use_calibrations_bladj function

<dl><dt>phy</dt>
<dd>A <code>phylo</code> object with or without branch lengths.</dd>
<dt>calibrations</dt>
<dd>A <code>data.frame</code> of secondary calibrations for any pair of taxon
names in <code>phy</code>, usually obtained with <code>get_all_calibrations()</code>.</dd>
<dt>type</dt>
<dd>The type of age to use as calibration. Options are "median", "mean", "min", or "max".</dd>
<dt>root_age</dt>
<dd>Numeric specifying the age of the root. Only used if there are
no ages for the root node in <code>calibrations</code> argument.
If missing, NULL, or not numeric, the value of the oldest calibration plus one
unit of the mean differences across calibrations, will be used as root calibration.
If there is one single age point provided as <code>calibrations</code>, the root age will
be set to 10% more than the age of the single calibration.</dd></dl>
