Rmarkdown YAML header 中的作者隶属关系，使用 rticles

Question

我想将作者隶属关系添加到我的 YAML header，并且按照此处的建议 ()，使用 rticles::elsevier_article 输出格式非常好，并且也省略了第一页上的页码，这也是可取的。问题是 1) 文本引用定义在呈现为 pdf 时显示（它们不应该），2) 文本引用不起作用 - 调用它们只会导致显示调用文本（而不是引用文本），以及 3 ) 对 table 和数字的引用与 bookdown::pdf_document2 输出不同。我怎样才能在 bookdown::pdf_document2 输出中获取作者和页码，或者让参考文献在 rticles::elsevier_article 中工作？

下面是一个说明问题的示例。我正在使用 RStudio 1.2.1335。

The Problems I have
==========================

I would like to use the `rticles::elsevier_article` output because it 1) handles authors and affiliations the way I want, and 2) it nicely omits the page number from the firat page. Both of these things I can't seem to easily (if at all) accomplish using `bookdown::pdf_document2` output. 

However, when I specify `rticles::elsevier_article` output, I run into several problems: 1) text reference definitions are displayed upon rendering to pdf (they should not), 2) text references do not work - calling them results only in the text of the call (not the referenced text) being displayed, and 3) references to table and figures does not work as it does with `bookdown::pdf_document2` output. There is one more issue too - in one test case I inserted a table (using `kableExtra`), and knitting failed because of some latex `tabu` environment error, even though it looks to me like the `rticles::elsevier_article` output does indeed load the `tabu` package (but I had to load it in the YAML header to get the knitting to work). 

For example, lets define a text reference so I can use a super script 2 to specify square kilometers in a figure caption. The reference definition should not show in the rendered pdf (and it does not when I use the `bookdown::pdf_document2` output, but it frustratingly does so when I use the `rticles::elsevier_article` output).

<!-- text references for use in tables and captions (must be separated by empty line)-->
(ref:km2) km^2^

Now lets make a figure (below) and reference it here (Figure \@ref(fig:testfig)). The figure includes the text reference in the caption, but it does not display the referenced text, but only the exact text that is suppose to call the reference text. And my inline reference to the figure does not work.

```{r,testfig, echo=FALSE, fig.height = 2.5, fig.width = 3, fig.align = "center",fig.cap=paste0("This is a classic quadratic plot - it could represent ","(ref:km2)",".")}

x=-5:5

plot(x,x**2,xlab="my assets", ylab="my joy", main="Not true")

```

Answer 1

与 detailed in the documentation 一样，您可以将 bookdown 功能与其他格式相结合。在你的情况下，你必须更换

output: rticles::elsevier_article

和

output:
  bookdown::pdf_book:
      base_format: rticles::elsevier_article
