如何在 R markdown 的引用中仅提供年份？

Question

我的 rmarkdown 脚本如下所示：

---
title: "Untitled"
author: "me"
date: '`r format(Sys.time(), "%d %B, %Y")`'
output:
  pdf_document: default
  bibliography: bibliography.bib
---

In his book Helsel explains how to approach censored environmental data [@helsel_statistics_2012].

我的 .bib 文件是这样的：

@book{helsel_statistics_2012,
    address = {Hoboken, N.J},
    edition = {2nd ed},
    series = {Wiley series in statistics in practice},
    title = {Statistics for censored environmental data using {Minitab} and {R}},
    isbn = {978-0-470-47988-9},
    publisher = {Wiley},
    author = {Helsel, Dennis R.},
    year = {2012},
    note = {00003 OCLC: ocn748290711},
    keywords = {Environmental sciences, Measurement Statistical methods, Minitab, Pollution, R (Computer program language), Statistical methods},
}

当我编织文件时，我得到以下输出：

Helsel 在他的书中解释了如何处理经过审查的环境数据（Helsel 2012）。

问题：如何才能return只在引用中注明年份（因为我已经在文中注明了作者）？

在他的著作 Helsel (2012) 中解释了如何处理被审查的环境数据。

Answer 1

在 rmarkdown (.Rmd) 文件中放入以下内容（注意从 [@helsel_statistics_2012] 中删除 [ ] 括号）：

In his book @helsel_statistics_2012 explains how to approach censored environmental data.

渲染后将为您提供所需的输出：

In his book Helsel (2012) explains how to approach censored environmental data.

如果您真的只想要引文中的年份，那么：

[-@helsel_statistics_2012]

returns:

(2012)
