R闪亮:乳胶方程式无法正确呈现 [英] R Shiny: Latex equations are not properly rendered

问题描述

我无法通过滑坡来渲染乳胶方程.一个简单的例子是:

I can't get ioslides to render latex equation. A simple example is:

---
title: "Title"
author: "Author"
date: "Tuesday, November 03, 2015"
output: ioslides_presentation
runtime: shiny
---

## slide 1

$\sum_{i=1}^n X_i$

The equation is rendered as \(\sum_{i=1}^n X_i\

请注意，如果我将文件创建为 RPresentation 而不是 ioslides，我可以获得正确的渲染.

Note that I'm able to get the proper rendering if I create the file as RPresentation but not as ioslides.

推荐答案

ioslides需要知道它必须使用mathjax

ioslides needs to know that it has to use mathjax
