Inclusion of preamble.tex

R Markdown
#1

I have a problem with generating a PDF.

The yaml file contains:

bookdown::pdf_book:
  includes:
    in_header: preamble.tex

The process works in that a complete PDF is produced in the _book directory, but it then runs again to generate a PDF in the top directory. This second process fails because TeX/LaTeX packages included via preamble.tex are not included.

So, what is going on? What am I missing.

I don't know why you get two rendering. When does this happen ? When you run bookdown::render_book() ?
When you render all formats ?

What is the content of your _output.yml ? Of you index.Rmd yaml header ?

Good point.

bookdown::render_book()

generates the file in _book only, but the Rstudio Build button tries to build a second version in the parent directory. As can be seen from the log it actually uses a different command (far fewer arguments).

Must be an Rstudio peculiarity (it did not previously do this).

I will just use the command line.

_output.yaml content:

bookdown::pdf_book:
  includes:
    in_header: preamble.tex
  latex_engine: xelatex
  citation_package: natbib
  keep_tex: yes
  toc_depth: 4
  indent: true

Content of index.Rmd

--- 
title: "some title"
author: "some person"
date: "`r Sys.Date()`"
output: pdf_document
geometry: "left=2cm,right=2cm,top=2cm,bottom=2cm"
description: some description.
documentclass: book
link-citations: yes
bibliography: book.bib
site: bookdown::bookdown_site
biblio-style: apalike
---

These are fairly standard (I think).
