R markdown 在rmarkdown中使用\newenvironment

R markdown 在rmarkdown中使用\newenvironment,r-markdown,newenvironment,R Markdown,Newenvironment,我正在尝试在Rmarkdown文档中创建代码簿样式的环境,如下所示: --- title: "Title" author: "Author" date: "`r Sys.Date()`" output: pdf_document: fig_caption: yes fig_crop: yes keep_tex: no number_sections: yes citation_package:

Defining function here:

\newlength\cbl
\newenvironment{codebook}[1][]{
    \settowidth{\cbl}{#1}
    \parskip1em plus .3em minus .2em
    \parindent0pt
    \def\code##1##2{{\bfseries ##1}\hfill
        \parbox[t]{\dimexpr\linewidth-15em-\cbl}{##2}\par}}{\noindent}

\newpage

\singlespacing

Testing out the environment here: 

\subsubsection{Codebook}
    
\begin{codebook}
  \code{country}{Country name.}
  \code{year}{Year of country observation.}
  \code{codename}{Country code (character).}
  \code{codenumber}{Country code (numeric).}
\end{codebook}
我已确认
\newenvironment
代码在TeXstudio中正常工作,但当我尝试将此文档编入PDF时,我遇到以下错误:

! Undefined control sequence.
<argument> \code
!未定义的控制序列。
\代码

我假设
\newenvironment
命令中有一些东西不能很好地使用rmarkdown语法。任何帮助都将不胜感激。

如果您在YAML中设置了
keep_-tex:yes
,您可以得到错误的提示。从
\subsubsection{Codebook}
开始,您将看到

\subsubsection{Codebook}

\settowidth{\cbl}{\code}
    \parskip 1em plus .3em minus .2em
    \parindent 0pt
    \def\code#\code#
所以发生的事情是,潘多克试图处理 您的环境定义,而不是将其单独放置。通过如下方式输入定义,可以强制它忽略定义:

```{=latex}
\newlength\cbl
\newenvironment{codebook}[1][rob\_avprison1]{
    \settowidth{\cbl}{#1}
    \parskip1em plus .3em minus .2em
    \parindent0pt
    \def\code##1##2{{\bfseries ##1}\hfill
        \parbox[t]{\dimexpr\linewidth-15em-\cbl}{##2}\par}}{\noindent}
```

在您的示例中,这似乎足够了,但您可能需要在实际文档中包装更多内容。

谢谢!这适用于最低限度的示例和完整的文档。非常感谢。
