在RMarkdown中在单个图形中绘制多个图的问题 [英] Issues plotting multiple plots in a single figure within RMarkdown

问题描述

我有出图函数，可以生成四个像glm的图.直方图，箱线图和两个散点图.但是我不能将它们放在文档中的正确位置，这样我才能看到所有信息.我想要1行中有2个图并且要宽一些，这样我就可以看到所有信息，例如标题等.

I have plot function that produce four plots like glm. A histogramm, a boxplot and two scatterplots. But I cant put them in the right place in my document so that I can see all informations. I want 2 plots in 1 row and to be wide so I can see all informations like header etc.

发布我的plot函数是没有意义的，因为它是针对我创建的类的.

It's senseless to post my plot function, because it's for a class that I created.

我的输出看起来总是这样

My output looks always like this

我具有以下YAML布局:

I have the following YAML layout:

---
title: 
author:
fontsize: 11
graphics: true
documentclass: article
output: 
  pdf_document:
    fig_caption: yes
    toc: true
    latex_engine: pdflatex
    toc_depth: 2
    number_sections: true
    keep_tex: true
header-includes: 
- \usepackage{graphicx}
- \usepackage{float}
- \usepackage{subfig}
---

```{r setup, include = FALSE}
library(knitr)
knitr::opts_chunk$set(fig.path = 'figures/', fig.pos = 'htb!', echo = TRUE)
knit_hooks$set(plot = function(x, options)  {
  hook_plot_tex(x, options)
})
```

```{r, out.width='1\\linewidth', fig.asp=0.5, fig.ncol = 1, fig.cap="output",fig.align = "center"}
par(mfrow = c(1, 2))
plot(poisReg)
```

推荐答案

我无法复制您的问题.使用一组可重复的图:

I am failing to replicate your problem. Using a reproducible set of plots:

---
title: 
author:
fontsize: 11
graphics: true
documentclass: article
output: 
  pdf_document:
    fig_caption: yes
    toc: true
    latex_engine: pdflatex
    toc_depth: 2
    number_sections: true
    keep_tex: true
header-includes: 
- \usepackage{graphicx}
- \usepackage{float}
- \usepackage{subfig}
---

```{r setup, include = FALSE}
library(knitr)
knitr::opts_chunk$set(fig.path = 'figures/', fig.pos = 'htb!', echo = TRUE)
knit_hooks$set(plot = function(x, options)  {
  hook_plot_tex(x, options)
})
```

```{r, out.width='1\\linewidth', fig.asp=0.5, fig.ncol = 1, fig.cap="output",fig.align = "center"}
par(mfrow = c(1, 2))
plot(cars, main = "Title 1")
plot(cars, main = "Title 2")
plot(cars, main = "Title 3")
plot(cars, main = "Title 4")
```

在我看来，设置figures文件夹的编织器有些混乱.

It seems to me that something is being messed up the knitr setting up the figures folder.
