### Packaging Project Files for Publisher - Shell

Source: https://github.com/hadley/adv-r/blob/master/README.md

This shell script prepares the 'Advanced R' book's source files for publishing. It creates a 'crc' directory, copies all necessary book components including LaTeX files, bookdown generated files, diagrams, screenshots, emoji, and other assets, then removes specific temporary files before zipping the entire 'crc' directory into a single archive.

```Shell
mkdir crc
cp _book/_main.tex crc
cp -r _bookdown_files/*_files crc
cp -r diagrams crc
cp -r screenshots crc
cp -r emoji crc
cp mina.jpg crc
cp krantz.cls crc
cp book.bib crc
rm crc/diagrams/*.graffle

zip -r adv-r-source.zip crc
```

### Initializing Google Analytics with gtag.js (JavaScript)

Source: https://github.com/hadley/adv-r/blob/master/ga_script.html

This snippet initializes the Google Analytics `dataLayer` and configures the `gtag.js` library. It sets up the global `gtag` function, sends a 'js' command with the current date, and configures a specific Google Analytics tracking ID (UA-141212623-1) for data collection.

```JavaScript
window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'UA-141212623-1');
```
