how do you publish rCharts with knitHTML

问题

I am trying to publish rCharts in knitrHTML, I keep getting this error:

Quitting from lines 11-43 (ddd.Rmd) 
Error in file(con, "w") : cannot open the connection
Calls: <Anonymous> ... <Anonymous> -> <Anonymous> -> <Anonymous> -> writeLines -> file

Execution halted

this is my kode within the markdown:

rPlot(cpubusy ~ datetime, color = 'machine', type = 'point', data = server)

How could I resolve this? what am I missing?

See - Ramnath answer.

Basically to add rCharts and have it rendered within knitr you need to the print method and include_assets = TRUE. This will tell knitr to add the JS and CSS assets required for rCharts.

Also make sure you have {r results = 'asis', comment = NA} for your chunk.

```{r results = 'asis', comment = NA}
   p <- rPlot(speed ~ dist, data = cars, type = 'point')
   p$print('chart', include_assets = TRUE)
```
