Examples

Introduction

The purpose of beautier is to create a valid BEAST2 XML input file from its function argument. 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 (website at https://github.com/ropensci/babette). babette allows to use BEAST2 (and its tools) from R.

Getting started

For all examples, do load beautier:

library(beautier)

Each example shows a picture of a BEAUti dialog to achieve the same. BEAUti is part of the BEAST2 tool suite and it’s a GUI to create BEAST2 input files. beautier is an R package to supplement BEAUti, by providing to do the same from an R script.

Each example reads the alignment from a FASTA file called anthus_aco_sub.fas, which is part of the files supplied with beautier:

input_filename <- get_beautier_path("anthus_aco_sub.fas")

In this vignette, the generated BEAST2 XML is shown. Use create_beast2_input_file to save the resulting XML directly to file instead.

Example #1: all default

Using all default settings, only specify a DNA alignment.

create_beast2_input(
  input_filename
)
