小编msh*_*fer的帖子

我想为hline着色,例如:

\hline[color=red,width=2mm,dashed]

或者其他的东西.

以下是一次失败的微弱尝试.我把textcolor灰色放在{|}试图让它变灰.理想情况下,我希望它是灰色和虚线.还要注意{\hline}标签周围的textcolor灰色.任何帮助将不胜感激使用乳胶语法.

有属性\hline吗？如果是这样,文档在哪里？有一个原因我喜欢php.net以满足我的其他编程需求.

    \begin{array}{c\textcolor{gray}{|}cccccccccc}
 & \textcolor{gray}{P_1} & \textcolor{gray}{P_2} & \textcolor{gray}{P_3} & \textcolor{gray}{P_4}  & \textcolor{gray}{P_5} & \textcolor{gray}{P_6} & \textcolor{gray}{P_7} & \textcolor{gray}{P_8} & \textcolor{gray}{P_9} & \textcolor{gray}{P_{10}}\\
 \textcolor{gray}{\hline}
\textcolor{gray}{P_1}   &0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_2}   & 0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_3}   &0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_4}   &0&1&1&0&0&0&0&0&0&0\\
\textcolor{gray}{P_5}   &1&1&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_6}   &0&0&0&0&0&0&0&0&0&0\\
\textcolor{gray}{P_7}   &1&1&0&0&1&1&0&0&0&0\\
\textcolor{gray}{P_8}   &1&0&0&1&0&1&0&0&0&0\\
\textcolor{gray}{P_9}   &0&0&1&0&0&0&0&0&0&0\\
\textcolor{gray}{P_{10}}  &0&0&0&0&0&1&0&1&0&0
\end{array}

动机

我想构建一个基于各种最优性度量的包排名算法。

我今天读了一些东西 [tidyverse]，它指向以下命令：

元素

tools::package_dependencies(package="liteq", recursive=TRUE)[["liteq"]]

它可以很容易地包装到一个函数中（正在进行中）：

help.packageInfo = function(package, key="dependencies", ...)
    {
    # number of authors
    # function to PARSE DESCRIPTION FILE
    
    tools::package_dependencies(package=package, recursive=TRUE)[[package]];
    }

示例[好]

help.packageInfo("digest");

示例[不好]

help.packageInfo("tidyverse");
