推荐答案

您可以使用以下设置根据输出格式进行切换

You could use the following setup to switch according to the output format

```{r, echo=FALSE}
out_type <- knitr::opts_knit$get("rmarkdown.pandoc.to")
keep <- if(out_type == "html") 'none' else 'last'
```


```{r chunk, echo=FALSE, fig.keep=keep}
plot(cars)
if(out_type == "html")
  cat("there goes fancy js code")
```
