我正在使用以下 R markdown 文件生成以下 Tex 文件。我在我的 .rmd 标头中包含 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.

This is a proof.
end{proof}
编译时给出以下输出：
> require(rmarkdown); render('RA01-notes.rmd')
Loading required package: rmarkdown
