如何修改 knitr 输出块

Question

我知道可以调整knitr代码块的输出，使其看起来符合您的要求。我在使用该parskip包时遇到了问题。该parskip包在代码输出下方添加了额外的空间，看起来不太好。这是一个最小.Rnw文件。

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[margin=1in]{geometry}
\usepackage{parskip}

\begin{document}
\setlength{\parindent}{0in}
Some text above chunk
<<echo=TRUE>>=
2 + 2
@
Some text below. The space above this is too big when using the \texttt{parskip} package.

Some text below. The space above this is too big when using the \texttt{parskip} package.

A nice space between paragraphs.
\end{document}

Answer 1

这不是一个优雅的答案，但您可以通过包含负垂直空间来“修复”多余的空间。请参阅修改后的代码。

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[margin=1in]{geometry}
%\usepackage{parskip}

\begin{document}
\setlength{\parindent}{0in}
Some text above chunk
<<echo=TRUE>>=
2 + 2
@
\vspace{-1em}  %%% this moves the following text up the height of an 'm'
