我一直在Mac上通过RStudio成功使用RMarkdown。

最近升级到RStudio 1.2.5019和tinytex_0.18，现在我的“标题栏”和“第一个正文/标题”之间的垂直间距增加了。

一个简单的示例（故意排除author:和date:）是：

---
output: 
  pdf_document
title: "Example of Title to Body Text"
subtitle: Subtitle Places Here
---
This is the first paragraph (or heading if specified as such). It is quite a way down from the title of the document. How can this be reduced to a "single line" vertical space?

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

然后，我尝试使用“ titlesec”包，但无法确定要使用哪个命令来实现所需的结果。尝试的示例是：

---
output: 
  pdf_document

subparagraph: yes
header-includes: |
  \usepackage{titlesec}
  \titlespacing{\title}{0pt}{\parskip}{-\parskip}

title: "Example of Title to Body Text"
subtitle: Subtitle Places Here
---
This is the first paragraph (or heading if specified as such). It is quite a way down from the title of the document. How can this be reduced to a "single line" vertical space?

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

这就是当前呈现为PDF的外观。

这就是我希望PDF看起来更像的东西（从图形程序编辑）。

那么，如何减小标题栏和文档正文开头之间的垂直间距？

提前致谢。
