How do I provide only the year in a citation in R markdown?

My rmarkdown script looks as follows:

---
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].

MY .bib file as such:

@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},
}

When I knit the file I get the following output:

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

Question: How can I return the year only in the in citation (as I already state the author in the text)?

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

In the rmarkdown (.Rmd) file put the following (note the removal of [ ] brackets from [@helsel_statistics_2012]):

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

Once rendered this will give you the desired output:

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

If you really only want the year from the citation then:

[-@helsel_statistics_2012]

returns:

(2012)
