latex - 减少RMarkdown中对齐环境和文本内容之间的垂直空间

Question

我正在写带有方程式的rmarkdown pdf文档(使用mac，knitr，pdf-latex)。我的问题是rmarkdown会自动在前面的文本和公式之间创建2-3行的大空白间隙。我如何摆脱这种差距？

下面的示例rmarkdown文档。

- \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

这里有两个选择。正如我在评论中指出的，的第一个仅用于使用\vspace。 第二个是使用\abovedisplayskip。有关此(以及同级命令)如何工作的详细信息，我可以向您推荐Remove vertical space around align。
