在RStudio 0.98.94中使用Knitr HTML的googlevis问题

Question

When using RStudio 0.97, I used to be able to easily knit googleVis plots into html output. However, now using RStudio 0.98.94, it causes an error even for the following Rmd:

---
title: "knitr googleVis"
output: html_document
---

```{r, results='asis'}
library('googleVis')
tbl <- gvisTable(data.frame(letters = letters[1:5], number = seq(5)))
print(tbl, 'chart')
```

The error message is:

pandoc.exe: Failed to retrieve https://www.google.com/jsapi?callback=displayChartTableID253831656700

InternalIOException getAddrInfo: does not exist (error 11001)

Error: pandoc document conversion failed with error 61

In addition: Warning message:

In if (grepl(" ", path, fixed = TRUE)) path <- utils::shortPathName(path) : the condition has length > 1 and only the first element will be used

Execution halted

The following is my sessionInfo():

Does anyone have any ideas on fixing this? Thanks a lot!

Knitr不会渲染googleVis或devtools::install_github('mages/googleVis')对我devtools::install_github('mages/googleVis') 。
