DSLC Mastering Shiny Book Club

Welcome to the DSLC Mastering Shiny Book Club!

We are working together to read Mastering Shiny by Hadley Wickham. Join the #book_club-mshiny channel on the DSLC Slack to participate. As we read, we are producing notes about the book.
You can catch up on Book Club recordings on the Mastering Shiny YouTube Playlist.

How to Present

This repository is structured as a {bookdown} site. To present, follow these instructions:

Do these steps once:

1. Setup Git and GitHub to work with RStudio (click through for detailed, step-by-step instructions; I recommend checking this out even if you're pretty sure you're all set).
2. usethis::create_from_github("r4ds/bookclub-mshiny") (cleanly creates your own copy of this repository).

Do these steps each time you present another chapter:

1. Open your project for this book.
2. usethis::pr_init("my-chapter") (creates a branch for your work, to avoid confusion, making sure that you have the latest changes from other contributors; replace my-chapter with a descriptive name, ideally).
3. devtools::install_dev_deps() (installs any packages used by the book that you don't already have installed).
4. Edit the appropriate chapter file, if necessary. Use ## to indicate new slides (new sections).
5. If you use any packages that are not already in the DESCRIPTION, add them. You can use usethis::use_package("myCoolPackage") to add them quickly!
6. Build the book! ctrl-shift-b (or command-shift-b) will render the full book, or ctrl-shift-k (command-shift-k) to render just your slide. Please do this to make sure it works before you push your changes up to the main repo!
7. Commit your changes (either through the command line or using Rstudio's Git tab).
8. usethis::pr_push() (pushes the changes up to github, and opens a "pull request" (PR) to let us know your work is ready).
9. (If we request changes, make them)
10. When your PR has been accepted ("merged"), usethis::pr_finish() to close out your branch and prepare your local repository for future work.
11. Now that your local copy is up-to-date with the main repo, you need to update your remote fork. Run gert::git_push("origin") or click the Push button on the Git tab of Rstudio.

When your PR is checked into the main branch, the bookdown site will rebuild, adding your slides to this site.

Example Shiny Apps

If you create any shiny apps to illustrate the concepts in a chapter, you are welcome to include them with your chapter notes. The apps should be placed in the ./examples/ directory of the repository.

Create a subdirectory named ./examples/<chapter-number>_<chapter-name>_<app-description> for each of the apps you create and place your app.R file in there.

For example, if while working on chapter 3 ("Basic Reactivity"), you create an app to illustrate controlling the timing of evaluation, you might add your app as ./examples/03-basic_reactivity-timing_evaluation/app.R.

Images

If any static image files are used in the .Rmd for a chapter, please add them into the directory ./images/<chapter_number>-<title_stub>/. For example, to include images for the "01-your_first_shiny_app" chapter, please place them in ./images/01-your_first_shiny_app/.
