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.
First, beautier is loaded:
A BEAST2 XML input file needs an alignment (as BEAST2 infers
phylogenies and parameters on DNA sequences). This demonstration uses a
testing FASTA file used by beautier:
We can display the alignment in the file:
Specify the filename for our XML file, here I use a temporary filename, so there is no need to clean up afterwards:
output_filename <- get_beautier_tempfilename()
output_filename
[1] "~/.cache/beautier/file48fb11ae48a1"Now we can create our XML file. We do not specify any inference model, and just use the BEAUti default settings:
The file indeed is a BEAST2 input file:
readLines(output_filename)
