[Tex/LaTex] Loading Custom Fonts into RMarkdown

fontsfontspecknitrrrstudio

I've been testing loading my own fonts into a personal rmarkdown document using the fontspec latex package. Because I'll eventually need to knit this on a server, using the font library on my mac is not an option and I need to refer to a specific filepath.

I've been at this for a while and while the fonts seem to load, the latex compilation will throw an error where the \begin{document} latex tag will not be recognized in the .tex document generated by rmarkdown even though the the tag will be in the .tex file. Does anyone have a solution for this or a workaround for getting custom fonts in from a local filepath?

I'm using RStudio Version 1.1.453 and Latex Version 3.14159265-2.6-1.40.19.

To load the fonts I've used the following convention in my YAML header specified by this post:

---

title: "Test Report" 
author: "me"
geometry: left = .5cm, right = .5cm, top = 3cm, bottom = 3cm
output:`
pdf_document:
 keep_tex: yes
 latex_engine: lualatex
header-includes:
 - \usepackage{wallpaper}
 - \usepackage{fontspec}
 - \pagenumbering{gobble}
 - \setmainfont[Path = ~/Desktop/Typography/ , UprightFont =  font1 , ItalicFont = font2 , BoldFont =  font3 , Extension = .otf]{common_filenames}

~ is an active character denoting a non breaking space, you need \string~ to get a literal ~

Option 1: Using `knit_child()` with inline R code

Say your setup is like the following. In the same directory, you have:

`graph.R`

## ---- graph
library(ggplot2)
CarPlot <- ggplot() +
    stat_summary(data= mtcars,
                 aes(x = factor(gear),
                     y = mpg
                 ),
                 fun.y = "mean",
                 geom = "bar"
                 )
CarPlot

`chapter1.Rnw`

Hey, look, a graph (Figure~\ref{fig:graph})!

<<graph, echo=FALSE, message=FALSE, fig.lp='fig:', out.width='.5\\linewidth', fig.align='center', fig.cap="A graph", fig.pos='h!'>>=
@

`main.Rnw`

\documentclass{article}

\begin{document}

<<external-code, echo=FALSE, cache=FALSE>>=
read_chunk('./graph.R')
@

\Sexpr{knit_child('chapter1.Rnw')}

\end{document}

Then, you can knit the main.Rnw file and compile the resulting .tex file with either pdflatex or xelatex.

The output is:

Note that you can also read the external .R file from the child .Rnw file.

So, the following would have worked just as well.

`chapter1-mod.Rnw`

<<external-code, echo=FALSE, cache=FALSE>>=
read_chunk('./graph.R')
@

Hey, look, a graph (Figure~\ref{fig:graph})!

<<graph, echo=FALSE, message=FALSE, fig.lp='fig:', out.width='.5\\linewidth', fig.align='center', fig.cap="A graph", fig.pos='h!'>>=
@

`main-mod.Rnw`

\documentclass{article}

\begin{document}

\Sexpr{knit_child('chapter1-mod.Rnw')}

\end{document}

Option 2: Using chunk option `child`

Assuming you have graph.R and chapter1.Rnw from above in the same directory, then your main.Rnw should be:

\documentclass{article}

\begin{document}

<<external-code, echo=FALSE, cache=FALSE>>=
read_chunk('./graph.R')
@

<<child-demo, child='chapter1.Rnw'>>=
@

\end{document}

Note that you can also read the external .R file from within the child document in this case, too.

So, assuming you had graph.R and chapter1-mod.Rnw from above in the same directory, then your main-mod.Rnw file should be:

\documentclass{article}

\begin{document}

<<child-demo, child='chapter1-mod.Rnw'>>=
@

\end{document}
