R Markdown PDF中上图的图标题 [英] Fig caption above figure in R Markdown PDF

问题描述

我想知道如何使字幕显示在R Markdown中的图形上方.

这是一个可行的示例:

  ---标题:实用"输出:pdf_document:fig_caption:是的latex_engine:xelatex---```{r fig1，echo = FALSE，fig.cap ="\\ label {fig:fig1}标题"}x ＜-1:10y<-11:20情节(x，y)``` 

在

I was wondering how I could get my captions to appear above my figures in R Markdown.

Here is a working example:

---
title: "Practical"
output:
  pdf_document:
    fig_caption: yes
    latex_engine: xelatex
---

```{r fig1, echo=FALSE, fig.cap="\\label{fig:fig1}Caption"}
x <- 1:10
y <- 11:20
plot(x, y)
```

The question has been asked before here, but the code suggested does not seem to work for me.

解决方案

When RMarkdown is run, it converts the base document to a LaTeX document using pandoc. As a result, we LaTeX packages can be used within the document, which can help in achieving advance customisation like this.

In this case, the Floatrow package can be used to reposition the caption above the figure. This is largely based of this previous answer. It can be loaded by including header-includes argument within the YAML, as follows:

---

title: "Practical"
output:
  pdf_document:
    fig_caption: yes
    latex_engine: xelatex
header-includes:
   - \usepackage{floatrow}
   - \floatsetup[figure]{capposition=top}
---


```{r fig1, echo=FALSE, fig.cap="\\label{fig:fig1}Caption"}
x <- 1:10
y <- 11:20
plot(x, y)
```
