This tutorial provides an introduction to creating websites using R, R Markdown and GitHub pages.
Updates were made on November 6, 2020 to simplify the personal website example as some extraneous pieces of information there were giving people problems. See new example website for my cats, John and Pete!
The current version was updated and presented at the R Ladies NYC Meetup on February 15, 2018.
This tutorial was originally presented at the Memorial Sloan Kettering Cancer Center Department of Epidemiology and Biostatistics R User Group meeting on January 23, 2018.
The main types of websites you may want to create include:
The minimum requirements for an R Markdown website are:
index.Rmd: contains the content for the website homepage
_site.yml: contains metadata for the website
A basic example of a
_site.yml file for a website with
name: "my-website" navbar: title: "My Website" left: - text: "Home" href: index.html - text: "About" href: about.html
And a basic
index.Rmd to create the Home page:
--- title: "My Website" --- Hello, Website! Welcome to the world.
You can find an overview of R Markdown website basics here.
This tutorial will focus on hosting websites through GitHub pages. Hosting websites on GitHub pages is free.
If you don’t have a GitHub account already, sign up for one at https://github.com/join?source=header-home with username YOUR_GH_NAME. I’ll be referring to this username, YOUR_GH_NAME, as “your GitHub username” throughout this tutorial.
There are other free sites for website hosting, and another popular choice is Netlify.
Let’s say that I wanted to build a website for my cats.
There are two main steps for creating a personal website that will be hosted on GitHub:
index.Rmdfile in your new directory
The R Project is useful because RStudio will recognize your project as a website, and provide appropriate build tools.
Note: After creating the R Project and initial files, you may need to close the project and reopen it before R will recognize it as a website and show the appropriate build tools.
_site.yml file to change the metadata, layout,
and theme of your website. Preview Jekyll themes here and play around with different
options. Themes are easy to change even after you have added
For example, the
_site.yml for my cats’ personal website
looks like this:
name: "cat-website" navbar: title: "My cats' website" left: - text: "Home" href: index.html right: - icon: fa-envelope fa-lg href: mailto:<firstname.lastname@example.org> - icon: fa-github fa-lg href: http://github.com/<YOUR_GH_NAME>/ output: html_document: theme: darkly
Choose a default theme from https://bootswatch.com/3/ for easy implementation.
Edit and create
.Rmd files that contain your website
content, which will produce the html pages of your website when you knit
For example, the
index.Rmd file for my cats’ personal
website homepage looks like this:
--- title: "My cats have a website!" --- This is John. <img src="files/john.jpg" style="width:50%"> This is Pete. <img src="files/pete.jpg" style="width:50%"> They are brothers! <img src="files/brother_kitties.jpg" style="width:50%">
In this example the image files are stored in a subdirectory of YOUR_GH_NAME.github.io named “files”.
Once you have your content written and the layout setup, on the Build tab in RStudio, select “Build Website”:
Now your local directory contains all of the files needed for your website:
And here’s what the resulting website looks like, hi kitties!
Advanced approach (recommended):
The default is for your site to be hosted at http://YOUR_GH_NAME.github.io, but you can add a custom domain name as well. There are two steps:
It will appear like this in your repository:
And inside the file you will simply have your domain name:
An example from the website for my package
Use Hadley Wickham’s great package
pkgdown to easily
build a website from your package that is hosted on GitHub. Details of
pkgdown can be found on the pkgdown website, which was also
This assumes you already have an R package with a local directory and a GitHub repository.
From within your package directory run:
This will add a folder called
docs to the local
directory for your package
Upload/push these changes to the GitHub repository for your package
In the GitHub repository for your package go to Settings > GitHub pages. Select “master branch/docs folder” as the source and hit Save
The page will be added as to your personal website as YOUR_GH_NAME.github.io/repo_name
The Home page of the site will be pulled from the README file on your package repository
The Reference page of the site lists the included functions with their description
Each function can be clicked through to see the help page, if any
Would also build pages for any available vignettes
And you’re done, it’s that easy.
You can create a website for a non-package repository as well. For example, I have a page on my website linking to the repository in which this tutorial is stored.
From within the local directory of the project of interest:
index.Rmdfile in your new directory
Upload/push these new files to the GitHub repository for your project
Enable GitHub pages for the repository by going to Settings > GitHub Pages, where you’ll select the “master branch” folder and hit Save
R Markdown websites are simple to create and deploy, but can become
cumbersome if you make frequent updates or additions to the website, as
in the case of a blog. Luckily, the R package
exists just for this purpose.
blogdown is an R package that
allows you to create static websites, which means that the deployed
images. Luckily the
blogdown package makes it so that you
don’t have to know any of those things to create a beautiful website for
your blog, powered by Hugo.

I don’t have a personal blog, so let’s look at the website I built to feature the events and blog of the R-Ladies NYC organization as an example.
The first three steps are similar to those from creating a basic R Markdown website:
Next we get started with
Choose a theme and find the link to the theme’s GitHub repository. In this case themes aren’t quite as easy to change as with basic R Markdown websites, so choose carefully.
Within your project session, generate a new site. The option
theme_example = TRUE will obtain the files for an example
site that you can then customize for your needs. Below “user/repo”
refers to the GitHub username and GitHub repository for your selected
blogdown::new_site(theme = "user/repo", theme_example = TRUE)
This will generate all of the file structure for your new blog.
After this is complete, you should quit and then reopen the project. Upon reopening, RStudio will recognize the project as a website.
Make changes to the
config.toml file (equivalent to the
_site.yml from basic R Markdown websites) to change the
layout and appearance of your website. The available features of the
config.toml file will differ depending on your theme, and
most theme examples come with a well annotated
that you can use as a template.
Once you have customized your website features, click on the RStudio addin “Serve Site” to preview the site locally.
There are several ways to create a new post for your site, but the easiest is using the RStudio addin “New Post”:
This opens a pop-up where you can enter the meta-data for a new post:
In addition to setting the Title, Author and Date of the post, you can additionally create categories, which will organize your posts in folders, and can add tags to posts, which can make them searchable within your site’s content. Be aware that the functioning of these features will vary by theme. Dates can be in the future to allow future release of a post.
Notice at the bottom that you can select whether to use a regular

.Rmd files will have to be rendered before generating html
pages so it is best practice to limit their use to cases where R code is
A file name and slug will automatically be generated based on the other metadata. The slug is a URL friendly title of your post.
blogdown site is a bit more cumbersome both to build
and to host on GitHub as compared to a regular R Markdown website, and
as compared to what I described above.
Problem 1: Because it is a static site, upon building, the
files needed to generate the site online are automatically created in a
separate subdirectory called
public within your local
directory. However this will cause problems with GitHub hosting since
the files to host need to be in the local YOUR_GH_NAME.github.io

Problem 2: GitHub defaults to using Jekyll with website
content, and this needs to be disabled since
are built with Hugo
To get around this, you need to include an empty file named
.nojekyll in your GitHub repo YOUR_GH_NAME.github.io, prior
