JSS模板中的作者为Rticles叠加，不知道如何将它们分成两行

Question

我正在尝试撰写统计软件期刊（JSS）的手稿，我有四位作者，问题是当我编写手稿时，作者的隶属关系是叠加的。我在JSS的Articles with many authors中看到他们将它们分成两行，但我没有找到任何方法在Rticles包中做到这一点，这是一个有4位作者的示例手稿

  - name: Main author

```{r, echo=FALSE, warning=FALSE, message=FALSE}
library(rticles)
library(rmarkdown)
library(yaml)
```

```{r, echo=FALSE, warning=FALSE}
library(knitr)
opts_chunk$set(prompt=TRUE)
options(replace.assign=TRUE, width=90, prompt="R> ")
