This is built with the R package blogdown.
This set of files was created using the Rstudio interface and selecting File -> New Project -> New Directory -> Website Using Blogdown
To build the website and load it into a web browser, run blogdown::serve_site()
To deploy the website on GitHub pages, the public/ directory should be the GIT repository. Also, you will need to put a .nojekyll file inside the public/ directory. So, after creating the .nojekyll file, initialize the GIT repository in the public/ directory, then push it to a new GitHub repo, then go to the Settings tab for the repository, scroll down to the GitHub Pages section, and set the source to master branch
