Rmarkdown投影仪: How to left justify the title page

Question

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，默认为中心:

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

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

## R Markdown

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.

您可以使用以下命令切换到左对齐标题页

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

要在 rmarkdown 中使用它，请将此行放在名为 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

使用最新版本的markdown，你也可以直接做

---
title: "Untitled"
author: "S SS"
date: "2/4/2018"
output: 
  beamer_presentation
header-includes:
  - \setbeamertemplate{title page}[default][left]
