降价到PDF中的标题和无花果标题问题答案

【问题标题】：Problem with header and fig captions in markdown to PDF降价到PDF中的标题和无花果标题问题
【发布时间】：2019-04-05 22:53:27
【问题描述】：

我正在尝试让我的数字字幕正常工作，但我遇到了一些问题。要么我的字幕无法正常工作，要么我的标题将显示在图下方。

我尝试过将 \newpage、\pagebreak、\ 在所有可能的位置、fig.pos、fig.height 和 fig.width 上，但似乎没有任何效果。无法同时显示标题和图上的标题。

这是我的代码：

output: pdf_document
fig_caption: yes
graphics: yes
keep_tex: yes
---

### Header(Will get under the plot in the pdf)

```{r plot, fig.cap="Hello World!"}
ggplot(data, aes(x=x, y=y)) + geom+point()
```
Text text text text text text text

@Oscar，我无法重现您的问题。我确实必须稍微调整您的代码才能使其正常工作：

---
output: pdf_document
fig_caption: yes
graphics: yes
keep_tex: yes
---

### Header(Will get under the plot in the pdf)

```{r plot, fig.cap="Hello World!"}

library(ggplot2)
ggplot(mtcars, aes(x=mpg, y=cyl)) + geom_point()

```
