Question

我正在用方程式编写rmarkdown pdf文档（使用mac，knitr，pdf-latex）。我遇到的问题是rmarkdown会自动在前面的文本和等式之间创建2-3行的大空白间隙。我如何摆脱这种差距？

以下示例rmarkdown doc。

title: "No More Gaps"
author: "Llew Mills"
date: "16th of September 2016"
output: pdf_document
header-includes:
- \setlength{\mathindent}{0pt}
linestretch: 1.3
toc: yes
classoption: fleqn
---

Some text to illustrate the gap. I still want there to be a decent line spacing between lines of text, but I would like a much smaller gap between the equations and the preceding text.

\begin{align*}
Y_{ij} &= \pi_{0i} + \pi_{1i}TIME_{ij} + \pi_{2i}(0) + \varepsilon_{ij}\\
&= \pi_{0i} + \pi_{1i}TIME_{ij} + \varepsilon_{ij}
\end{align*}
\endgroup

Can anyone help with this problem?

Answer 1

这里有两种选择。正如我在评论中指出的那样，第一个就是使用\vspace。 第二个是使用\abovedisplayskip。有关此（以及兄弟命令）如何工作的详细信息，我可以推荐您Remove vertical space around align。

header-includes:
  - \usepackage{amsmath}
  - \usepackage{lipsum}

\setlength{\abovedisplayskip}{-15pt}
\setlength{\belowdisplayskip}{0pt}
\setlength{\abovedisplayshortskip}{0pt}
\setlength{\belowdisplayshortskip}{0pt}
\lipsum*[3]
\begin{align*}
  A\cap B & = \{b,d,e\} \cap \{a,b,f,g\} \\
          & = \{b\}
\end{align*}
\lipsum[3]
