Rmarkdown yaml中的多个作者和字幕

Question

我正在尝试关注this pandoc example 将多个作者添加到yaml metadata block 中的Rmarkdown 文件中。 pdf 将在 RStudio（版本 0.98.932）中生成，但没有作者信息。

---
title:  'This is the title: it contains a colon'
author:
- name: Author One
  affiliation: University of Somewhere
- name: Author Two
  affiliation: University of Nowhere
date: "`r format(Sys.time(), '%d %B %Y')`"
tags: [nothing, nothingness]
abstract: |
  This is the abstract.

  It consists of two paragraphs.
output: pdf_document
---

我还想进一步自定义标题并添加副标题。可能吗？

Answer 1

我刚刚发现可以在 R markdown PDF 输出中添加字幕。我在 Ubuntu 14.04 中使用 R 3.2.2 和 RStudio 0.99.473。

---
title:  'This is the title: it contains a colon'
subtitle: 'This is the subtitle'
output: pdf_document
---

Answer 2

rmarkdown 中默认的 Latex 模板不支持作者单位或字幕。它确实支持多个作者，但是正确的 yaml 语法是

---
title:  'This is the title: it contains a colon'
author:
- Author One
- Author Two
date: "`r format(Sys.time(), '%d %B %Y')`"
tags: [nothing, nothingness]
abstract: |
  This is the abstract.

  It consists of two paragraphs.
output: 
    pdf_document:
        template: NULL

如果您想自定义标题，最好的方法是修改乳胶模板found here 以满足您的需求。然后将其复制到您的本地目录并将其传递给template 字段中的标题。

Answer 3

如主要答案中所述，默认的 R Markdown 模板不支持作者从属关系。虽然用户可以编辑模板文件以添加他们自己的自定义 YAML 字段，但您可以使用一些更简单的解决方法来输出 PDF 或 HTML。

HTML 输出

您可以使用最近发布的radix template。首先你必须安装包：

install.packages("radix")

一旦安装，您必须设置

title: "Radix for R Markdown"
description: | 
  Scientific and technical writing, native to the web
date: May 4, 2018
author:
  - name: "JJ Allaire"
    url: https://github.com/jjallaire
    affiliation: RStudio
    affiliation_url: https://www.rstudio.com
  - name: "Rich Iannone"

output: radix::radix_article

Your content

PDF 输出

您可以使用预制模板，rticles 包中有一些很好的示例。首先我们必须安装包：

install.packages("rticles")

安装后，您可以使用其中一种模板，例如 Journal of Statistical Software：

---
author:
  - name: FirstName LastName
    affiliation: University/Company
    address: >
      First line
      Second line
    email: \email{name@company.com}
    url: http://rstudio.com
  - name: Second Author
    affiliation: Affiliation
title:
  formatted: "A Capitalized Title: Something about a Package \\pkg{foo}"
  # If you use tex in the formatted title, also supply version without
  plain:     "A Capitalized Title: Something about a Package foo"
  # For running headers, if needed
  short:     "\\pkg{foo}: A Capitalized Title"
abstract: >
  The abstract of the article.
keywords:
  # at least one keyword must be supplied
  formatted: [keywords, not capitalized, "\\proglang{Java}"]
  plain:     [keywords, not capitalized, Java]
preamble: >
  \usepackage{amsmath}
output: rticles::jss_article

Answer 4

如果您呈现 pdf，LaTex 使用作者的脚注作为附属关系（即转换符号中的编号）。试试

---
title:  'This is the title: it contains a colon'
subtitle: 'This is the subtitle'
author:
- Author One^[University of Somewhere]
- Author Two^[University of Nowhere]
date: "`r format(Sys.time(), '%d %B %Y')`"
tags: [nothing, nothingness]
abstract: |
  This is the abstract.

  It consists of two paragraphs.
output: pdf_document

Answer 5

我在这里找到了问题的字幕部分的解决方案：https://stackoverflow.com/a/41444545/14027216

您可以通过在代码中添加subtitle:来添加字幕，并且可以添加多个字幕，如下所示：

---
title:  'This is the title: it contains a colon'
subtitle: |
  | 'subtitle 1'
  | 'subtitle 2'
author:
- name: Author One
  affiliation: University of Somewhere
- name: Author Two
  affiliation: University of Nowhere
date: "`r format(Sys.time(), '%d %B %Y')`"
tags: [nothing, nothingness]
abstract: |
  This is the abstract.

  It consists of two paragraphs.
output: pdf_document
---

您可以添加两个以上的字幕，但我不知道最大数量。每个字幕都会换行显示。

Answer 6

我也遇到过这个问题。根据@tmpname12345 的建议，我修改了latex 模板（default.tex）和html 模板（default.html）来渲染字幕。如果您想要快速获取代码，此拉取请求位于 github rstudio/rmarkdown，并且看起来它将在下次推送到 CRAN 时成为 rmarkdown 中的标准。

Answer 7

添加到 Ze Grisi 的答案，我刚刚发现将 html 标题标签添加到 yaml 作品中以调整标题和副标题中的字体。请注意不再需要引号。

---
title:  'This is the title: it contains a colon'
subtitle: <h1>This is the subtitle</h1>
output: pdf_document
---

要获得更戏剧化的效果，请在副标题中添加下划线

---
title:  'This is the title: it contains a colon'
subtitle: <h1><u>This is the subtitle</u></h1>
output: pdf_document

Answer 8

@greg 在enter link description here 使用乳胶解决方案。我将乳胶代码放入 rmarkdown yaml 标头 进行了一些更改，它完成了这项工作。

---
title: 'Some Title'
author: Author One$^1$ \and 
        Author Two$^2$ \and
        Author Three$^3$ 
date: $^1$Organization 1 \newline
      $^2$Organization 2 \newline
      $^3$Organization 3 
    \newline  
    \newline
    \today 
output: 
---

诀窍是将隶属关系放入 date 标记中。
