问题描述
在Rmarkdown之外,单独的googleVis图表可以正常工作,但是当我将其插入Rmarkdown文件时,我仅收到Rmarkdown代码:
Outside of Rmarkdown the stand alone googleVis chart works fine, but when I plug it in the Rmarkdown file I am receiving just the Rmarkdown Code:
查看器输出:
> TEST H 4/13/2016 require(googleVis) Loading required package:
> googleVis Welcome to googleVis version 0.5.10 Please read the Google

> g1=gvisAnnotationChart(dttm,datevar="DT_ENTRY",numvar="value",idvar="variable")
> plot(g1) starting httpd help server ... done
Rmarkdown代码如下:
Rmarkdown Code Below:
---
title: "test"
author: "H"
date: "4/13/2016"
output: html_document
highlight: tango
number_sections: yes
---
```{r}
require(googleVis)
dttm = data.frame(DT_ENTRY=Sys.Date()-1:20,variable="x",value=1:20)
g1=gvisAnnotationChart(dttm,datevar="DT_ENTRY",numvar="value",idvar="variable")
plot(g1)
```
推荐答案
r块必须声明为:
```{r plotg0, results='asis', tidy=FALSE, echo=FALSE}
便捷性"很重要,因为它会返回原始HTML
The "asis" is important because it returns raw HTML
