R Markdown Notebook



Collapsible code sections in RStudio, but have noticed this option is not there when working in R Notebook (as opposed to a source file. R Markdown is a format for writing reproducible, dynamic reports with R. Use it to embed R code and results into slideshows, pdfs, html documents, Word files and more. To make a report. An R Notebook is an R Markdown document with chunks that can be executed independently and interactively, with output visible immediately beneath the input. They are similar to R Markdown documents with the exception of results being displayed in the R Notebook creation/edit mode rather than in the rendered output. Use a productive notebook interface to weave together narrative text and code to produce elegantly formatted output. R Markdown supports dozens of. I would like to convert a rmarkdown.Rmd document to a jupyter notebook.ipynb.I found that converting from jupyter to rmd is easy using as described in reference page but for some reason (.) the.

Learning Objectives

After completing this tutorial, you will be able to:

  • Add an image to an R markdown report.
  • Describe the ideal location to store an image associated with an R markdown report so that knitr can find it when it renders a file.

What You Need

You need R and RStudio to complete this tutorial. Also you should have an earth-analytics directory set up on your computer with a /data directory with it.

Add an Image to Your Report

You can add images to an R Markdown report using markdown syntax as follows:

However, when you knit the report, R will only be able to find your image if you have placed it in the right place - RELATIVE to your .Rmd file. This is where good file management becomes extremely important.

To make this simple, let’s set up a directory named images in your earth-analytics project / working directory. If your .Rmd file is located in the root of this directory and all images that you want to include in your report are located in the images directory within the earth-analytics directory, then the path that you would use for each image would look like:

images/week3/image-name-here.png

Let’s try it with an actual image.

And here’s what that code does IF the image is in the right place:

If all of your images are in your images directory, then knitr will be able to easily find them. This also follows good file management practices because all of the images that you use in your report are contained within your project directory.

Today we’re excited to announce R Notebooks, which add a powerful notebook authoring engine to R Markdown. Notebook interfaces for data analysis have compelling advantages including the close association of code and output and the ability to intersperse narrative with computation. Notebooks are also an excellent tool for teaching and a convenient way to share analyses.

You can try out R Notebooks today in the RStudio Preview Release.

Interactive R Markdown

As an authoring format, R Markdown bears many similarities to traditional notebooks like Jupyter and Beaker. However, code in notebooks is typically executed interactively, one cell at a time, whereas code in R Markdown documents is typically executed in batch.

R Notebooks bring the interactive model of execution to your R Markdown documents, giving you the capability to work quickly and iteratively in a notebook interface without leaving behind the plain-text tools and production-quality output you’ve come to rely on from R Markdown.

Same editor/tools used for R scripts
Works well with version control
Focus on production output
Output inline with code
Output cached across sessions

Iterate Quickly

In a typical R Markdown document, you must re-knit the document to see your changes, which can take some time if it contains non-trivial computations. R Notebooks, however, let you run code and see the results in the document immediately. They can include just about any kind of content R produces, including console output, plots, data frames, and interactive HTML widgets.

You can see the progress of the code as it runs:

You can preview the results of individual inline expressions, too:

Even your LaTeX equations render in real-time as you type:

This focused mode of interaction doesn’t require you to keep the console, viewer, or output panes open. Everything you need is at your fingertips in the editor, reducing distractions and helping you concentrate on your analysis. When you’re done, you’ll have a formatted, reproducible record of what you’ve accomplished, with plenty of context, perfect for your own records or sharing with others.

Batteries Included

R Notebooks can run more than just R code. You can run chunks written in other languages, like Python, Bash, or C++ (Rcpp).

It’s even possible to run SQL directly:

This makes an R Notebook an excellent tool for orchestrating a reproducible, end-to-end data analysis workflow; you can easily ingest data using your tool of choice, and share data among languages by using packages like feather, or ordinary CSV files.

Reproducible Notebooks

While you can run chunks (and even individual lines of R code!) in any order you like, a fully reproducible document must be able to be re-executed start-to-finish in a clean environment. There’s a built-in command to do this, too, so it’s easy to test your notebooks for reproducibility.

Rich Output Formats

Since they’re built on R Markdown, R Notebooks work seamlessly with other R Markdown output types. You can use any existing R Markdown document as a notebook, or render (knit) a notebook to any R Markdown output type.

The same document can be used as a notebook when you’re quickly iterating on ideas and later rendered to a wholly different format for publication – no duplication of code, data, or output required.

Share and Publish

R Markdown List

R Notebooks are easy to share with collaborators. Because they’re plain-text files, they work well with version control systems like Git. Your collaborators don’t even need RStudio to edit them, since notebooks can be rendered in the R console using the open source rmarkdown package.

Rendered notebooks can be previewed right inside RStudio:

R Markdown Notebook Tutorial

While the notebook preview looks similar to a rendered R Markdown document, the notebook preview does not execute any of your R code chunks; it simply shows you a rendered copy of the markdown in your document along with the most recent chunk output. Because it’s very fast to generate this preview (again, no R code is executed), it’s generated every time you save the R Markdown document.

The generated HTML file has the special extension .nb.html. It is self-contained, free of dependencies, and can be viewed locally or published to any static web hosting service.

It also includes a bundled copy of the R Markdown source file, so it can be seamlessly opened in RStudio to resume work on the notebook with all output intact.
