--- title: "R Notebook" output: html_notebook --- The [R plugin](https://www.jetbrains.com/help/pycharm/r-plugin-support.html) for IntelliJ-based IDEs provides handy capabilities to work with the [R Markdown](https://www.jetbrains.com/help/pycharm/r-markdown.html) files. To [add](https://www.jetbrains.com/help/pycharm/r-markdown.html#add-code-chunk) a new R chunk, position the caret at any line or the code chunk, then click "+". The code chunk appears: ```{r} ``` Type any R code in the chunk, for example: ```{r} mycars <- within(mtcars, { cyl <- ordered(cyl) }) mycars ``` Now, click the **Run** button on the chunk toolbar to [execute](https://www.jetbrains.com/help/pycharm/r-markdown.html#run-r-code) the chunk code. The result should be placed under the chunk. Click the **Knit and Open Document** to build and preview an output.
