GoogleVis排行榜沒有Rmarkdown渲染

Question

外Rmarkdown的獨立googleVis表工作正常，但是當我插上它，我只是接受Rmarkdown守則Rmarkdown文件：

查看器輸出：

> TEST H 4/13/2016 require(googleVis) Loading required package: 
> googleVis Welcome to googleVis version 0.5.10 Please read the Google 
> API Terms of Use before you start using the package:

> 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) starting httpd help server ... done 

Rmarkdown下面的代碼：

--- 
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) 
``` 

Answer 1

將R塊都將被聲明爲：

```{r plotg0, results='asis', tidy=FALSE, echo=FALSE} 

的「現狀」是很重要的，因爲它返回原始的HTML
