自动引用第 n 位作者

Question

我正在和很多人一起写一篇论文，说实话，目前我甚至不确定最终版本中会将谁列为作者。在正文中，我想写“推测的第四十二位作者”之类的内容，但事先不知道“42”（好吧，我必须承认，实际上我们没有那么多人）。

有没有办法给作者贴上标签来实现这一点？

Answer 1

这不是一个纯 LaTeX 解决方案，但如果您使用 R，则knitr有一个简单的方法：

\documentclass{article}
\usepackage{parskip}
<<theverylonglistofauthors,echo=F>>=
authors <- c(
"Davy Jones ",
"Hannibal Lecter",
"Norman Bates",
"Freddy Krueger",
"Jack Torrance", 
"Darth Vader",
"James Moriarty"
)
@
\title{We are legion}
\author{\Sexpr{combine_words(authors[1:3], sep=" \\and ", and="")}}
\date{\today}

\begin{document}
\maketitle
\section{Introduction}
