r - Knitr - 更改图表中段落之间的空格失败

Question

我想减少我的 Rnw 文件（LateX+R+Knitr）中块之间的空间。我遇到了以下适用于文本输出的 Rnw 文件：https ://gist.github.com/yihui/2760395#file-knitrout-parskip-rnw 。如果您有图表，则没有 - 图表向上移动太远，代码和图表重叠。是否有可能重新定义 knitrout 以影响输出文本而不是图表？我不知道如何附加 pdf 输出，但下面是代码。

\documentclass{article}

% change the space between paragraphs in chunks

\ifdefined\knitrout
  \renewenvironment{knitrout}{
    \setlength{\parskip}{-1in}
  }{
    \setlength{\parskip}{0in}
  }
\else
\fi

\makeatletter
\preto{\@verbatim}{\topsep=-1em \partopsep=-1em }
\makeatother
