R Markdown-并排定位表和绘图

Question

我正在使用R Markdown输出到pdf，并且试图将表格和绘图水平并排对齐。我可以得到fig.align = "right"来将图对齐到页面的右侧，但是它被绘制在表格的下方（格式为kable），而不是并排放置。有提示吗？

Answer 1

这是使用TeX软件包floatrow的一种方式：

---
title: "Untitled"
header-includes:
  - \usepackage{floatrow}
output: 
  pdf_document:
    keep_tex: true
---

\newfloatcommand{btabbox}{table}

\begin{figure}[H]
  \begin{floatrow}
    \ffigbox{%
```{r, fig.align = "right", echo = F}
plot(mpg ~ hp, data = mtcars)
```
    }{\caption{A figure}}

    \btabbox{%
```{r, fig.align = "right", echo = F}
knitr::kable(head(mtcars[,1:3]), format = "latex")
```
    }{\caption{A table}}
  \end{floatrow}
\end{figure}

Answer 2

我更喜欢Martin的方法，但是如果您想要一个不太依赖LaTeX的解决方案，则可以将表格转换为网格图形并plot it as a subfigure：

---
header-includes:
  - \usepackage{subfig}
output: pdf_document
---

```{r, fig.cap='two plots', fig.subcap= c('A figure', 'A table'), out.width = '.49\\linewidth', echo = F, fig.align='center'}
library(gridExtra)
library(grid)

plot(mpg ~ hp, data = mtcars)

grid.newpage()
grid.table(head(mtcars[,1:6]), theme = ttheme_minimal())
```

Answer 3

我能够结合使用multicol软件包和小型页面来做到这一点。另一个选择...

代码如下：

---
title: "Untitled"
header-includes:
  - \usepackage{multicol}
  - \newcommand{\btwocol}{\begin{multicols}{2}}
  - \newcommand{\etwocol}{\end{multicols}}
output: 
  pdf_document:
    keep_tex: true
---

```{r minipage_funs, echo = FALSE}
## adding minipages in Rmarkdown only seems to work for me when returned from function
fig_table_mp_start <- function() {
  return("\\begin{minipage}{\\textwidth}")
}
fig_table_mp_end <- function() {
  return("\\end{minipage}")
}
```

`r fig_table_mp_start()`

\btwocol

```{r, fig.align = "right", echo = FALSE}
plot(mpg ~ hp, data = mtcars)
```


```{r, fig.align = "right", echo = FALSE}
knitr::kable(head(mtcars[,1:3]), format = "latex")
```

\etwocol

`r fig_table_mp_end()`

我认为您可以尝试使用填充物使它看起来更漂亮。
