r - 如何仅提供R Markdown 引用中的年份？

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文件如下:

@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},
}

编织文件时，将得到以下输出:

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:如何仅在被引证的情况下返回年份(因为我已经在文本中说明了作者)？

在他的书Helsel (2012)中解释了如何处理受审查的环境数据。

Answer 1

在rmarkdown(.Rmd)文件中，添加以下内容(请注意，从[@ helsel_statistics_2012]中删除了[]方括号):

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用的年份，那么:

[-@helsel_statistics_2012]

返回:

(2012)
