Code in the notebook is executed with the same gestures you would use to execute code in an r markdown document: Use the green triangle button on the toolbar of a code chunk that has the tooltip Run Current Chunk, or Ctrl Shift Enter (macOS. Press Ctrl Enter (macOS: Cmd Enter) to run just the current statement. Running a single statement is much like running an entire chunk consisting only of that statement. There are other ways to run a batch of chunks if you click the menu run on the editor toolbar, such as Run All, run All Chunks Above, and Run All Chunks Below. The primary difference is that when executing chunks in an r markdown document, all the code is sent to the console at once, but in a notebook, only one line at a time is sent. This allows execution to stop if a line raises an error. There is also a restart r and Run All Chunks item in the run menu on the editor toolbar, which gives you a fresh R session prior to running all the chunks. This is similar to the Knit button, which launches a separate r session to compile the document.

3.2.1 Using Notebooks Creating a notebook, you can create a new notebook in RStudio with the menu command File - new File - r notebook, or by using the html_notebook output writing type in your documents yaml metadata. title: "my notebook" output: html_notebook, by default, rstudio enables inline output (Notebook mode) on all r markdown documents, so you can interact dissertation with any r markdown document as though it were a notebook. If you have a document with which you prefer to use the traditional console method of interaction, you can disable notebook mode by clicking the gear button in the editor toolbar, and choosing Chunk output in Console (Figure.4 ). Figure.4: Send the r code chunk output to the console. If you prefer to use the console by default for all your r markdown documents (restoring the behavior in previous versions of RStudio you can make chunk output in Console the default: tools - options - r markdown - show output inline for all. Inserting chunks, notebook chunks can be inserted quickly using the keyboard shortcut Ctrl Alt i (macOS: Cmd Option i or via the Insert menu in the editor toolbar. Because all of a chunks output appears beneath the chunk (not alongside the statement which emitted the output, as it does in the rendered r markdown output it is often helpful to split chunks that produce multiple outputs into two or more chunks which each. To do this, select the code to split into a new chunk (Figure.5 and use the same keyboard shortcut for inserting a new code chunk (Figure.6 ). Figure.5: Select the code to split into a new chunk. Figure.6: Insert a new chunk from the code selected before.
Figure.3: An r notebook example. R notebooks are an implementation. Literate Programming that allows for direct interaction with R while producing a reproducible document with publication-quality output. Any r markdown document can be used as a notebook, writing and all r notebooks can be rendered to other r markdown document types. A notebook can therefore be thought of as a special execution mode for r markdown documents. The immediacy of notebook mode makes it a good choice while authoring the r markdown document and iterating on code. When you are ready to publish the document, you can share the notebook directly, or render it to a publication format with the Knit button.
