beautier is BEAUti for R.

The purpose of beautier is to create a valid BEAST2 XML input file from a n inference model. In this way, a scientific pipeline using BEAST2 can be fully scripted, instead of using BEAUti’s GUI.

beautier is part of the babette package suite:

  • beautier create a BEAST2 input (.xml) file from an inference model.
  • tiebeaur creates an inference model from a BEAST2 input (.xml) file ⚠️ experimental ⚠️
  • beastier runs BEAST2
  • tracerer pastes BEAST2 output (.log, .trees, etc) files.
  • mauricer install BEAST2 packages

See examples.


beautier can be installed:

  • Latest CRAN version: CRAN
  • Latest stable version: GitHub, master branch
  • Bleeding-edge version: GitHub, develop branch


For the latest CRAN version:


GitHub, master branch

For the latest stable version:


GitHub, develop branch

For the bleeding-edge version:

remotes::install_github("ropensci/beautier", ref = "develop")

This works, and the interface is unlikely to change.

  • 1 DNA alignment
  • Site models:
    • JC69
    • HKY
    • TN93
    • GTR
  • Clock models:
    • Strickt
    • Relaxed log-normal
  • Tree models:
    • Yule
    • Birth-Death
    • Coalescent Bayesian Skyline
    • Coalescent Constant Population
    • Coalescent Exponential Population
  • Handle missing data: simply use a dash (´-´) as a sequence in a FASTA file


This works partially, and the interface may change as well.

Tip dating

The tip dates file is a file that needs to not have column, nor row names. The columns need to be tab separated.

See here for an example, of which the first rows are shown here:

KF767106_Indonesia_1976_VII 1976
KF767104_Indonesia_1988_VII 1988
KF767105_Indonesia_1988_VII 1988
AY288998_Indonesia_1990_VII 1990

In the future, there probably will be a ´to_tipdates_file´ function, to create a temporary tipdates file from a table.
