我如何从* .Rmd的HTML输出中获取带边框的(LaTeX数学)排版矩阵? [英] How do I get (LaTeX math) typeset matrix with borders in HTML output from *.Rmd?

问题描述

以下rmarkdown在编译为PDF(通过LaTeX)时可以正常工作，但在编译为HTML(通过Markdown)时不能正常工作.

The following rmarkdown works fine when compiling to PDF (via LaTeX), but not when compiling to HTML (via Markdown).

PDF(通过LaTeX)

---
title: "test"
author: "Maximilian Held"
output: pdf_document
documentclass: memoir
---

(@matrix-test2) $$
\bordermatrix{
  ~       & Petra & Ingrid \cr
  Petra   & 1     & 0 \cr
  Ingrid  & 0     & 1 \cr
}
$$

HTML(通过Markdown)

---
title: "test"
author: "Maximilian Held"
output: html_document
documentclass: memoir
---

(@matrix-test2) $$
\bordermatrix{
  ~       & Petra & Ingrid \cr
  Petra   & 1     & 0 \cr
  Ingrid  & 0     & 1 \cr
}
$$

这是怎么回事，这是谁的目的(Pandoc?Markdown?MathML?)

What's up with that and on whose end is this (Pandoc? Markdown? MathML?)

推荐答案

knitr ，通常用于使用 Pandoc 将RMarkdown转换为HTML/PDF(来自LaTeX)/DOCX. Pandoc是将Markdown转换为HTML和LaTeX的好工具，并允许您在Markdown内部使用LaTeX数学环境，例如

knitr, the tool normally used to convert RMarkdown to HTML/PDF (from LaTeX)/DOCX, uses Pandoc. Pandoc is a nice tool to convert Markdown to HTML and LaTeX and allows you to use LaTeX math environments inside Markdown, e.g.

$a x^2 + b x + c = 0$

或

$$a x^2 + b x + c = 0$$

或

\begin{equation}
a x^2 + b x + c = 0
\end{equation}

已由Pandoc正确转换. Pandoc还支持amsmath，这是一种非常流行的LaTeX数学软件包. 不幸的是，Pandoc不支持您发现的所有(La)TeX命令/环境.

are properly converted by Pandoc. Pandoc also supports the amsmath, a very popular LaTeX package for math. Unfortunately, Pandoc doesn't support all (La)TeX commands/environment as you discovered.

在与Pandoc合作时，我总是做的就是尽量简化事情.在您出现的情况下，我将使用普通表而不是矩阵.

What I always do when working with Pandoc is try to keep things simple. In the case you present, I would use normal tables instead of a matrix.
