Welcome to the Big Book of R repository! This repository hosts a collection of nearly 400 R programming books, most of which are freely available. The project is open to contributions of both free and paid books.

To work with this repository, you need to have some tools and libraries installed on your system:

• Quarto: We use Quarto to render the books. Make sure Quarto is installed on your machine.
• R Programming Environment: Ensure that R is installed.
• R Libraries: Install the following R libraries:

  library(dplyr)
  library(tidyr)
  library(stringr)
  library(googlesheets4)
  library(readr)

• R studio or Visual Studio Code (VS Code): This project is best managed using R studio or VS Code.

• _quarto.yml: The primary configuration file that manages the rendering of books and calls all .qmd files.
• chapters/: Directory where individual .qmd files are stored after fetching data from the Google Sheets.
• scripts/:
  • fetch_books.R: Script to fetch book data from Google Sheets, create .qmd files in the chapters directory, and generate the chapter_list.txt.
  • chapter_list.txt: Text file containing the list of .qmd files with their paths, generated by fetch_books.R.
• HTML files: these are part of the book rendering process.

1. Clone the repository to your local machine. Use the git command to clone the repository:

   git clone [repository-url]

2. Install all the prerequisites mentioned above. Ensure that all necessary tools and libraries, as specified in the project documentation, are installed on your system.

3. Ensure R and necessary libraries are installed. Use the following commands in your R console to install the required R packages if not already installed:

   install.packages("dplyr")
   install.packages("tidyr")
   install.packages("stringr")
   install.packages("googlesheets4")
   install.packages("readr")

4. Run the fetch_books.R script to automate data fetching. This script automatically populates the chapters directory and generates the chapter_list.txt file. It is designed to facilitate the addition of new book entries without needing manual updates to the project structure:

5. Preview the book locally. Immediately after running the fetch_books.R, preview the book using:

   quarto preview

   This step ensures that the newly fetched content renders correctly without errors.

6. Update the Quarto book structure for new chapters. If structural changes are required due to the addition of new chapters, manually update the _quarto.yml file:
   • Delete outdated content: Remove all content in the chapters directory and the existing chapter_list.txt file.
   • Re-run fetch_books.R: Fetch the latest data to reflect the new chapter entries and generate updated .qmd files.
   • Manually update _quarto.yml: Incorporate changes from the new chapter_list.txt into _quarto.yml to align with the new chapter structure.
   • Preview changes: Run quarto preview to verify that all updates are rendered correctly before committing the changes to the repository.

This revised documentation now clearly separates the automated process for adding new book entries from the manual process required for new chapter entries, including necessary updates to the _quarto.yml configuration.
