r - Tex Proof 环境未在 R Markdown 中定义，amsthm 未在生成的 Tex 文件中

Question

[编辑以提供更多信息]

我正在使用以下 R markdown 文件生成以下 Tex 文件。我在我的 .rmd header 中包含了 amsthm，它正在生成一个没有 amsthm 的 Tex 文件。因此，在编译期间未定义证明环境。

这是我的 .rmd 文件:

---
title: Real Analysis Notes 01
header_includes:
- \usepackage{amsthm}
 output:
  pdf_document:
   keep_tex: true
---

This is a test file.

\begin{proof}
This is a proof.
\end{proof}

编译后输出如下:

> require(rmarkdown); render('RA01-notes.rmd')
Loading required package: rmarkdown


processing file: RA01-notes.rmd
  |.................................................................| 100%
  ordinary text without R code


output file: RA01-notes.knit.md

pandoc 选项是 header-includes(连字符而不是下划线)。
