我在我的论文中修改参考文献引用风格时遇到了一些麻烦。根据r-markdown的说明，要指定bibliography样式（我需要来自latex的acm），只需执行以下操作：
---
title: "title"
bibliography: biblioteka.bib
biblio-style: acm
output:
pdf_document
---
然而，biblio-style: acm 似乎对引用样式没有影响。
当前的引用：
随机森林已经被应用于信用评分[@作者1]...
@Article{author1,
Title = {some title},
Author = {Einstein},
Year = {1997}
}
期望的输出:
随机森林已经应用于信用评分 [1]...
References
[1] Einstein, some title, 1997

之后在您的YAML头文件中引用此文件：
---
title: "title"
bibliography: biblioteka.bib
csl: acm.csl
output:
pdf_document
---
为了改变样式，只需在CSL-网站找到另一个引文样式，并按照不同的*.csl进行操作。
为了完整起见，在论文最后您需要添加参考文献：
# References
```{r refmgr references, results="asis", echo=FALSE}
# PrintBibliography(bib)
```
[51] Ong, C.S. et al. 2005. title. journal. 29 (1), (2005), 41–47.这是bib文件中的一部分。因此，输出应该是除了“et al.”之外，还要给出所有合著者的姓名。你能帮忙吗？@Article{ong2005, Title = {title}, Author = {Ong, C. S. and Huanga, J. J. and Tzeng, G. H.}, Year = {2005}, Journal = {journal}, Volume = {29 (1)} }- abe
