我如何僅在R markdown的引文中提供年份？

Question

我的rmarkdown腳本如下所示：

---
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},
}

當我編織文件時，我得到以下輸出：

在他的書中，Helsel解釋了如何處理審查的環境數據（Helsel 2012）。

問題：如何僅在引文中返回年份（因為我已經在文中說明了作者）？

在他的書中，Helsel （2012）解釋了如何處理審查的環境數據。

Answer 1

在rmarkdown（.Rmd）文件中輸入以下內容（注意從[@ helsel_statistics_2012]中刪除[]括號）：

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

一旦渲染，這將為您提供所需的輸出：

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

如果你真的只想要引用年份那么：

[-@helsel_statistics_2012]

收益：

(2012)
