我正在构建一个tufte::tufte_html应该包含对图形的交叉引用。不幸的是，我已经尝试了一整天无济于事。
下面，我还尝试了bookdown针对pdf_document2. 任何建议在这里都是宝贵的。

# Introduction
This is just an example
```{r examp-fig, fig.width=10, fig.cap="\\label{fig:examp-fig}Not a good caption"}
plot(2:5, 5:8)
```
## Try referencing here
Through the figure [@fig:examp-fig], I am trying to demonstrate how cross referencing works. But apparently this doesn't work.
Is this any better? The figure \@ref(fig:examp-fig) is being referenced here. Naaah!
