r-Rmarkdown yam中的多个作者和字幕

我正在尝试按照此pandoc示例将多个作者添加到yaml元数据块中的Rmarkdown文件中。 pdf将在RStudio（0.98.932版）中生成，但没有作者信息。

title: ‘This is the title: it contains a colon’
author:
– name: Author One
affiliation: University of Somewhere
– name: Author Two
affiliation: University of Nowhere
date: “r format(Sys.time(), '%d %B %Y')”
tags: [nothing, nothingness]
abstract: |

It consists of two paragraphs.
output: pdf_document
