我有一篇用 rnotebook 写的论文，我想把它编成 pdf。这是它的开始，包括 YAML：

title: "Are shifts between points of view challenging for readers? An examination of readers' eye movements in response to Woolf's *To the Lighthouse* and *Mrs Dalloway*"
author: "Giulia Grisot, Kathy Conklin, Violeta Sotirova - The University of Nottingham"
date: '`r format(Sys.time(), "%d %B %Y")`'
output:

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

```{r, include=F}
library(tidyverse)
library(ggpubr)
```

The emergence of empirical approaches within stylistics has increased interest in how literary texts are processed by readers. Techniques of speech and thought representation represent an area ripe for empirical investigation in this respect, especially when these cause interpretative ambiguities.

我已经安装了 tinytex，我已经安装了 miktex 和 pandoc。我试图在 RStudio 中使用“knit to pdf”命令，但它给了我这个错误，我不知道该怎么做

Error in yaml::yaml.load(..., eval.expr = TRUE) : 
  Scanner error: while scanning for the next token at line 4, column 31 found character that cannot start any token at line 4, column 31
Calls: <Anonymous> ... parse_yaml_front_matter -> yaml_load -> <Anonymous>
Execution halted
