Question

将R版本从3.3.3更新到3.4.2后，我的flexdashbords不再工作

运行这个简单的例子时：

---
title: "Flexdash Layout Test"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
---

```{r setup, include=FALSE}
library(flexdashboard)
```

Page 1
===================================================

Column 1 {data-width=650}
-----------------------------------------------------------------------

### Chart A

```{r}
print('Chart A')
```

Column 2 {data-width=350}
-----------------------------------------------------------------------

### Chart B

```{r}
print('Chart B')
```

Page 2
===============================================

### Chart C

```{r}
print('Chart C')
```

结果如下： flexdash layout error

显然格式化语法不起作用。

提前感谢您提供解决该问题的任何提示

编辑：当我尝试该示例并选择html作为输出时，格式化结果看起来像预期的那样。

Plain text   

End a line with two spaces  
to start a new paragraph.   
*italics* and _italics_   
**bold** and __bold__

因此错误肯定与flexdashboard相关

此处记录了此问题：https://github.com/rstudio/flexdashboard/pull/150

基本上，pandoc 2.0默认默认为html5而不是html，这会破坏flexdashboard布局。

您有两种选择：

1）降级到pandoc 1.x

2）安装Github软件包，直到它被推送到CRAN。这为我解决了这个问题。

remove.packages("flexdashboard")
install.packages("devtools")
library("devtools")
install_github("rstudio/flexdashboard")

flexdashboard页面布局错误
