My little rmarkdown example is as follows:
---
# documentclass: article
output:
pdf_document:
latex_engine: xelatex
# linestretch: 1.5
fontsize: 18pt # 10pt
header-includes:
- \usepackage{lipsum}
- \usepackage{setspace}\doublespacing #\singlespacing
- \usepackage[shortlabels]{enumitem}
- \setlist{nosep}
- \setlist{noitemsep}
- \setcounter{enumi}{-1}
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## random
\lipsum
## R Markdown

I have two issues: changing fontsize from 10pt to 18pt is not working; commenting \setlist{nosep}, \setlist{noitemsep} and \setcounter{enumi}{-1} or not makes no difference. Why these happen since this example is quite simple? (ps: setspace works well)
18pt is not an allowed class option. With the default article class only a handful of normal sizes are defined. You can extent this by switching to the extarticle class which has the 17pt option:
