markdown - Authors and affiliations in the YAML of RMarkdown

Question

I know this question was already asked in the past in this forum (1, 2, 3). Before you mark this as duplicated, I tried all the answers with no success. Most of the questions were asked long ago, and some updates related with pandoc might affect nowadays results.

The issue is that I am writing a scientific paper using RMarkdown, and would like to export the results either in HTML, PDF or Word files.

More importantly is that there are 12 authors signing the papers. Some of the authors present more than one affiliation, and some authors presenting the same affiliation.

My question is very clear: How can I edit the YAML to include all the authors with all the affiliations in the YAML in order to export to different formats (HTML, PDF, DOC)?

I tried this YAML:

---
title: "My title"
author:
  - name: Mario Modesto-Mata^1,2^
    email: [email protected]
  - name: Christopher^1^
  - name: Seaghán Mhartain^2^
  - name: Rita Yuri Ynoue^1^
address:
  - code: 1
    address: Instituto de Astronomía, Geofísica e Ciências Atmosféricas, Universidade de S?o Paulo
  - code: 2

    number_sections: yes

PDF output

This is what I see when I export to PDF the .Rmd file:

Instead of the authors, I see true and no affiliations.

HTML output

I see the authors and not all the affiliation numbers. The affiliations themselves remain hidden.

DOCX output

Neither names nor affiliations appear in the final Word file.

My system

I am using the latest RStudio version (Version 1.1.453), running on Linux Mint 19 Cinnamon.

UPDATE: original example

Answer 1

There is, to the best of my knowledge, no one-size-fits-it-all solution as of now.

If the target was only PDF, I'd suggest rticles by RStudio. It's great.

A solution which also works with docx is more difficult. One possibility is to use pandoc Lua filters. The repository collecting useful filters contains two filters which will help you: scholarly-metadata and author-info-blocks. (Disclosure: I wrote these.)

Place the .lua files in your directory, change the YAML structure a bit, and instruct pandoc to run the filters:

    pandoc_args:

This will be the PDF output:

while this is what it looks like in Word:

The affiliation and contact information is added to the body text, which is why the toc is displayed above it.
