R natbib似乎无法与pdf_书籍/文章一起正常工作

在我的.Rmd文件中，我将.bib文件中的位置引用如下：“让我引用一篇文章：[@SampleTitle2016]。”

当我“编织当前”时，我希望有.tex文件，其中引用的文章由\cite、\citep或\citet命令提供

我注意到，如果在输出参数中省略“引文包：natbib”一行，引文将作为原始文本提供：

但是，如果添加上述行，.tex文件看起来更好，但由于某些原因，参考书目无法正确显示/（编译？）-我看到的是“？”而不是正确的引用：

我的.Rmd如下所示：

---
title: "Sample document"
abstract: "This is a sample abstract \\newline This is the second line of abstract \\par \\textbf{Keywords:} keywordA, keywordB"
author:
  - name: Mateusz Kędzior
    email: alice@example.com
    affiliation: Some Institute of Technology
    footnote: Corresponding Author
bibliography: bibliography_escaped.bib
output:
  bookdown::pdf_book:
    base_format: rticles::elsevier_article
    keep_tex: true
    citation_package: natbib
---

## Sample Text

Let me cite an article: [@SampleTitle2016].

Without natbib, in .tex file citep  command is not used in output .tex file.

An with natbib, it seems there's problem with bibliography compilation.

## References

@article{SampleTitle2016,
    title = "This is sample title only \{\k{A}\} \{\L{}\}",
    journal = "Some journal",
    volume = "99",
    number = "",
    pages = "21 - 31",
    year = "2018",
    note = "This is fake",
    url = "http://ImustChangedThatLinkBecauseSOdoNotALLOWletmeG",
    author = "Mateusz K\k{e}dzior and \.{Z}\k{a}\'{c}\l{} \'{Z}\k{e}\'{n}",

不使用

articles:：elsevier\u article

作为输出的原因是什么？有了YAML标题中的输出，一切正常。因为我需要参考文档中的图\@ref（图：压力）、表和小节\@ref（小节图）。如果我错了，请纠正我，但只有“bookdown”提供了交叉引用的可能性？我问过这个问题，所以：你可以参考一些图，看看这个例子：`

{r plot1，fig.height=5，fig.width=5，fig.cap=“Plot 1\\label{fig:plot1}”Plot（1:10，1:10）

例如，请参见figu\ref{fig:plot1}`我认为这是一个比较好的解决办法，因为你把标签放在了标题中。我在下一期中提到了这一点：但无论如何，感谢您的帮助为什么不使用
