rmarkdown数字未出现在pdf中

r-markdown latex

Jonas Striaukas · 技术社区 · 2 年前

我使用rmarkdown创建了一组幻灯片。我用乳胶加了一个数字 includegraphics 其如预期的那样工作。但是,当我添加一个通过R代码生成的图形时,“乳胶”图形就会消失。

最小代码示例

---
title: "TITLE"
author: "JS"
subtitle: SUBTITLE
output:
  beamer_presentation: 
    keep_tex: yes
  ioslides_presentation: default
fontsize: 14pt
---



# Example 

\begin{figure}[t]
  \centering
  \includegraphics[scale=0.25]{include_figure}
\end{figure}

---

# Add figure via R code

```{r, message = FALSE, warnings = FALSE, eval = TRUE, echo = TRUE}
plot(rnorm(100))

有什么建议我做错了什么吗?

出于某种原因,rmarkdown和/或pandoc认为添加

\makeatletter
\def\maxwidth{\ifdim\Gin@nat@width>\linewidth\linewidth\else\Gin@nat@width\fi}
\def\maxheight{\ifdim\Gin@nat@height>\textheight\textheight\else\Gin@nat@height\fi}
\makeatother
% Scale images if necessary, so that they will not overflow the page
% margins by default, and it is still possible to overwrite the defaults
% using explicit options in \includegraphics[width, height, ...]{}
\setkeys{Gin}{width=\maxwidth,height=\maxheight,keepaspectratio}

序言是个好主意。。。显然不是这样。

您可以通过指定图像的高度而不是比例因子来避免这个问题:

---
title: "TITLE"
author: "JS"
subtitle: SUBTITLE
output:
  beamer_presentation: 
    keep_tex: yes
  ioslides_presentation: default
fontsize: 14pt
---



# Example 

\begin{figure}
  \includegraphics[height=4cm]{example-image-duck}
\end{figure}

---

# Add figure via R code

```{r, message = FALSE, warnings = FALSE, eval = TRUE, echo = TRUE}
plot(rnorm(100))
```
