I am using Rmarkdown and Knitr using Rstudio.
The following both print script and output to html.
```{r}
summary(cars)
```
However the following will only print the output, that is embedded plot.
```{r, echo=FALSE}
plot(cars)
```
I have situation different than above, I want to present the script but should not run in html as this will take very long time (hours if not days) to run. So I just did was put comment sign.
```{r}
#summary(cars)
```
But I need a better way to do this - Is there any better way presenting script without running it.

Caching a code chunk in R Markdown R Markdown has a built-in caching feature that can be enabled by setting cache=TRUE in the chunk's header. The second time the chunk is run, both the visual output and any objects created are loaded from disk.
Hide source code: ```{r, echo=FALSE} 1 + 1 ``` Hide text output (you can also use `results = FALSE`): ```{r, results='hide'} print("You will not see the text output.") ``` Hide messages: ```{r, message=FALSE} message("You will not see the message.") ``` Hide warning messages: ```{r, warning=FALSE} # this will generate ...
