如何将我的 Rmarkdown beamer 演示文稿的标题页对齐到左侧而不是默认中心？

示例，默认居中：

---
title: "Untitled"
author: "S SS"
date: "2/4/2018"
output: beamer_presentation
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```

This is an R Markdown presentation. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document.

这是一个技巧，直到有人提出更好的答案：我们将放弃标准的投影仪标题幻灯片，只需将第一张幻灯片格式化为标题幻灯片：

---
output: beamer_presentation
header-includes:
  - \usepackage{color}
---

\color{blue}
\LARGE{\textbf{This is the title}}  
\color{black}
\vspace{0.2cm}
\large{Author Name}  
\large{February 4, 2018}

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```

您可以使用

简单地切换到左对齐的标题页

\setbeamertemplate{title page}[default][left]

要在 rmarkdown 中使用它，请将这一行放在一个名为 preamble.tex 的文件中并使用

---
title: "Untitled"
author: "S SS"
date: "2/4/2018"
output: 
  beamer_presentation:
    includes:
      in_header: preamble.tex

---
