Here's how to format Markdown cells in Jupyter notebooks: Headings Use the number sign (#) followed by a blank space for notebook titles and section headings: # for titles ## for major headings ### for subheadings #### for 4th level subheadings; Emphasis Use the following code to emphasize text: Bold text: string or.string. Italic text: string or.string. Markdown allows you to format text using simple, plain-text syntax and can be used to document code in a variety of tools, including Jupyter Notebook. Learn how to format text in Jupyter Notebook.

This post walks through how to install R on a Jupyter notebook, load in data and build a visualization. Start by installing python using homebrew.

Install python

Open Terminal and enter the following commands.

It should already be installed, in which case you’ll need to upgrade

Install jupyter

Next install the jupyter notebook

Install zmq

Install the following R packages

These packages can be installed using R or RStudio. They are also found in the jupyter-install-pkgs.R file.

Launch jupyter notebooks

Open a new terminal window, enter the following commands.

This will launch the jupter notebook. You’ll see this in your Terminal:

The jupyter notebook will open in the browser

Click on the New icon in the upper right corner of the Jupyter notebook and select R.

Click on the Untitled text next to the Jupyter on the top of the notebook and rename the file something meaningful.

Using jupyter notebooks

The Jupyter notebooks combine code cells with markdown (just like RStudio Notebooks). I’ll start this notebook with a markdown title cell.

As you can see, this cell has markdown syntax highlighting. If I want to see how the cell will look after running it, hold down control + return (this is how to run a cell in Jupyter notebooks).

Run some R code

Enter the following code in the next cell and run it (either by using control + return or clicking Run)

Let’s print a portion of a data frame to see what it looks like in Jupyter notebooks.

Tables look pretty in Jupyter!

Run ggplot in Jupyter

I’ll see how a ggplot2 visualization looks next. Enter the following commands into the next code cell (I turned off the warnings before and after the plot commands to get rid of all the excess output).

The graph output is directly beneath the cell! Beautiful!

Download options

Vscode Jupyter Markdown

Under File > Download as I can see I have the option to save this file as a .ipynb (which is a JSON file), .md, .r, and many others.

Happy coding!

What is it ...

mdmath allows to use Visual Studio Code as a markdown editor capable of typesetting and rendering TeX math.K,In fact it now reuses the built in markdown viewer. KaTeX works inside as a fast math renderer.

You can install the extension directly from Visual Studio Code Marketplace.

What is new in mdmath 2.5.0 ...

  • Markdown+Math is compatible with Pandoc. So with dollars namespace inline usage of $$..$$ math expressions will result in display math notation (output on separate line).
  • Multiline math expressions in blockquote blocks are supported.
  • Code size is reduced.
  • Regular expressions were simplified.
  • Runtime performance is improved.

Features

Simplify the process of authoring and live previewing markdown documents containing math formulas.This extension is a comfortable tool for scientists, engineers and students with markdown as their first choicedocument format.

  • Inline math
  • Display math
  • Formula numbering
  • Inline math with tables
  • Works offline.
  • Integrated in native markdown viewer. So after installing the extension, TeX math is properly displayed in the markdown preview window.
  • Based on markdown-it plugin markdown-it-texmath.
  • Using vscode's Markdown Extension API.
  • Editor view and Preview are synchronized while scrolling.
  • Copy resulting HTML code to the system clipboard.
  • Due to markdown-it-texmath's support of different formula delimiters, these are also available and user configurable with mdmath:
    • 'dollars' (default)
      • inline: $...$
      • display: $$...$$
      • display + equation number: $$...$$ (1)
    • 'brackets'
      • inline: (...)
      • display: [...]
      • display + equation number: [...] (1)
    • 'gitlab'
      • inline: $`...`$
      • display: ```math ... ```
      • display + equation number: ```math ... ``` (1)
    • 'julia'
      • inline: $...$ or ``...``
      • display: ```math ... ```
      • display + equation number: ```math ... ``` (1)
    • 'kramdown'
      • inline: $$...$$
      • display: $$...$$
      • display + equation number: $$...$$ (1)

Installation ...

... from inside of VSCode

Press F1 key inside of Visual Studio Code and type extension. Choose Extensions: Install Extensionand then select the Markdown+Math extension from the list.

FAQ

  • How to define my own CSS file for HTML export ?

    • Define it by the user setting mdmath.style as an absolute URL. So for an example you might choose mdmath.style: 'file://c:/mystyle/mystyle.css' with windows.
  • How to define and use macros ?

    • Define them in user settings. For example ...
    • Use them in your markdown document. For example ...
  • How to define macros in a user macro file?

    • Create a JSON file containing the macros and define its path in user settings. For example ...
    • Define the macros the same way as in the user settings.
    • User macro definition file has priority over user defined macro settings, which are ignored then.
  • Are there global predefined macros ?

    • No. Macros are user defined with user settings mdmath.macros. So they are available in all user specific markdown documents.
  • Can I write the HTML source to a file ?

    • Yes. Use the Markdown: Save Markdown+Math to Html command or the key binding Ctrl+K,.
    • The Html file is written to the folder where the markdown file resides in. This is the default.
    • You can change the destination folder by specifying a relative path to your working directory with the help of the user setting mdmath.savePath. So for an example you might choose mdmath.savePath: './html/${file.name}.html'.
  • Can I synchronously let the HTML source file update ?

    • Yes. Simply set the user setting mdmath.autosave: true for this (default is false).
    • Now, whenever you save your markdown file, the corresponding Html file is also saved.
    • The destination folder mdmath.savePath is used for this.
  • Formula highlighting is broken ?

    • It is implemented only for $ delimiters at present.
    • $ characters in markdown text are sometimes confused with math delimiters. Enclose them by backticks (`) then.
    • Formula highlighting is possible only for formulas on a single line. It breaks with every newline character.
    • Math highlighting is completely different from LaTeX math parsing.
  • Which functions does KaTeX support ?

    • See them listed at KaTeX Supported Functions and KaTeX Support Table.
  • What if I need to use the currency symbol $ also in my markup ?

    • It should be safe to use it. If in doubt escape it.
  • What are the restrictions with inline formulas ?

    • Whitespace after opening $ and before closing $ is not allowed.
    • Numeric character before opening $ and after closing $ is not allowed.
    • At least one character (whitespace ?) is required between two consecutive inline formulas.
    • Line break inside is not allowed.
  • What are the restrictions with display formulas ?

    • Not allowed inline of text.
    • Not allowed inside of tables. Use inline math there instead.
    • Blank lines before and behind required.
    • Restrictions for inline formulas do not apply.
  • Can I use math markup in blockquotes ?

    • We can use inline and display formulas in blockquote sections.
    • Multiline display math expressions require leading > characters on each line.
    • Multilevel blockquote sections work as expected.
  • Can I use math markup in code blocks ?

    • No, math markup in code blocks is shown - as expected - as markup. This is consistent now, but in contrast to mdmath versions prior to 2.0.
  • Can I access the HTML source of the markdown file ?

    • Yes. Use the Markdown: Clip Markdown+Math to Html command or the key binding Ctrl+K..
    • The markdown preview window has to be opened once for this in order to function properly.
    • You need to have the markdown source window activated here (not the preview window!).
    • Please note, that the resulting HTML source references 'CDN'-located remote css files. Change those references to local URL's if necessary.
  • Is PDF output supported ?

    • Not directly. In order to create *.pdf output from your Markdown you can create a *.html document first and print it then using a PDF printer or use Pandoc.
    • See Compiling Markdown into HTML.
  • Can I use custom CSS styles for the preview window ?

    • Yes. Set mdmath.style in user settings to the location of your custom CSS file. Its path must be relative to this extension root.
  • Can we store Latex macros with mdmath ?

    • Yes, there is a new section mdmath.globalMacros in package.json. Try to expand it with your own macros.
