Double spacing in rmarkdown pdf

Question

I use the following in Rmarkdown YAML for double space (there are other items in the YAML that I do not include here).

output: pdf_document
header-includes:
    - \usepackage{setspace}\doublespacing

But it double spaces everything, but I want not to double space in the title page. My title page contains title of the document (which is more than 2 lines), author affiliations (which is also several lines).

Please note that my output is pdf (not HTML or WORD doc). Other components in YAML is fine.

Answer 1

Move your \doublespacing command out of the header and use where you need it:

---
output: pdf_document
header-includes:
  - \usepackage{setspace}
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
