Rmd：访问'yaml\u元数据\u块`

在R Markdown中，如何准确地从非标头访问元数据

我的尝试不太奏效：

---
title: "My YAML block test"
output:
  pdf_document:
    md_extensions: +yaml_metadata_block
---

next we want to define some data on-the-fly using YAML:

---
myparam: somestring
---

And try using it in the document:

This is first attempt -  myparam is: $myparam$
This is second attempt - myparam is: `r print(myparam)`

---

不确定，但可能会有帮助。谢谢，我还没有弄清楚如何使用多个输入文件作为命令行参数，即pandoc main.md additional.yaml-to latex-from markdown，通过knitr调用pandoc
