WATCH OUT: This is neither an accurate replication nor an authoritative textbook.
I am writing this book as a text for others to read because that forces me to become explicit and explain all my learning outcomes more carefully. Please keep in mind that this text is not written by an expert but by a learner.
Text passages with content I am already familiar I have skipped. Section of the original text where I needed more in-depth knowledge I have elaborated and added my own comments resulted from my personal research.
Be warned! In spite of replicating most of the content this Quarto book may contain many mistakes. All the misapprehensions and errors are of course my own responsibility.
This Quarto book collects my personal notes, trials and exercises of Mastering Shiny by Hadley Wickham (Wickham 2021).
I am learning wot work with {shiny} because I want to develop a dashboard for investigating countries in world maps with values of different years. For instance I want to use the WHR data 2011, 2012, 2014-2024 and show the distributions of the ladder scores abount the countries of the world.
My text consists mostly of quotes from the Mastering Shiny book. Sometimes I have them changed slightly to adapt it to the flow of my notes. But I have not shown that it is a quote nor I jave referenced the position of the (semi)quotes in the book. As I am generally follow the book’s outline using the same text for headers, it should be clear where to find the quotes.
This means that most of the text in this Quarto book is not mine but comes from different resources.
My personal comments should be clear because most of the times it is a reflection about the book and my experiences with it.
I am using the {glossary} package (DeBruine 2023) to create links to glossary entries.
R Code 1 : Load glossary
## 1. Install the glossary package:
## https://debruine.github.io/glossary/
library(glossary)
## If you want to use my glossary.yml file:
## 1. fork my repo
## https://github.com/petzi53/glossary-pb
## 2. Download the `glossary.yml` file from
## https://github.com/petzi53/glossary-pb/blob/master/glossary.yml)
## 3. Store the file on your hard disk
## and change the following path accordingly
glossary::glossary_path("../glossary-pb/glossary.yml")If you hover with your mouse over the double underlined links it opens an window with the appropriate glossary text. Try this example: WHR.
WATCH OUT! Glossary is my private learning vehicle
I have added many of the glossary entries when I was working through other books either taking the text passage of these books I was reading or via an internet recherche from other resources. Sometimes I have added the source of the glossary entry as an abbreviation or as an URL. Many definitions were provided by the KI provided within the search of my Brave browser.
If you fork my repository of these notes then the glossary will not work out of the box. Load down the glossary.yml file from my glossary-pb GitHub repo, store it on your hard disk and change the path in the code chunk Listing / Output 1 accordingly.
In any case I am the only responsible person for the glossary text, especially if I have used text from other resources wrongly. Again: The main purpose of the glossary is to support my personal learning venture.
During coding I am following the Tidyverse Style Guide. For learning purposes I am practicing {shiny} in two modes:
app.R files as explained in the book. I create folders with the number of the chapters, eg., apps-01, apps-02. Inside of these chapter folders I put the folders for the {shiny} examples with self explanatory names so that one can get and distinguish the example files that all have the name app.R. Additionally I order these examples with numbers that represents their appearance in the text, e.g., 01-hello-world, 02-greetings1 03-greetings2, etc.{shinylive-r} instead {r} in the header.I am not using always the exact code snippets of the book, because I am not only replicating the code to see how it works but also to change the values of parameters to observe their influences.
In some of my book notes I provide files in the annex. They contain experiments not directly in line with the book but inspired by my reading of the book.
Often you will also find an annex file with a standardized short description of all my used packages, sometimes added with notes about my personal experiences with this package. An example of the standardized format gives you the following Glossary package.
Package Profile: glossary
Add glossaries to markdown and quarto documents by tagging individual words. Definitions can be provided inline or in a separate file.
There is a lot of necessary jargon to learn reading new books. The goal of {glossary} is to provide a lightweight solution for making glossaries in educational materials written in quarto or R Markdown. This package provides functions to link terms in text to their definitions in an external glossary file, as well as create a glossary table of all linked terms at the end of a section.
In the meantime {glossary} is for me a very important learning vehicle. Whenever an expression appears with a doubled underlined link I know that I will get more information by hovering the mouse over the underlined text.
There is a little inconvenience with abbreviation that could also be part of another glossary entry text string (e.g., API and Capital Income). My workaround is to end the short abbreviation with an additional ‘x’ and then to call the glossary with the x-version follwed by the text that should be appear in the document (e.g., r glossary(“APIx”, “API”)). This double format is a standard feature of the {glossary} package so that you can adapt the appearing text to the glossary entry (e.g., singular/plural or other grammar changes).

XXX: [DESCRIBE PRIVATE FUNCTION USED IN THIS BOOK]
| term | definition |
|---|---|
| APIx | An API, or application programming interface, is a set of defined rules that enable different applications to communicate with each other. It acts as an intermediary layer that processes data transfers between systems, letting companies open their application data and functionality to external third-party developers, business partners, and internal departments within their companies. (<a href="https://www.ibm.com/topics/api">IBM</a>) |
| Capital Income | Capital income is defined as the sum of property income, including dividends, interest gains, reinvested earnings on foreign direct investment, investment income disbursements and land rents ([Distributional National Accounts (DINA) for Austria, 2004-2016](https://wid.world/document/distributional-national-accounts-dina-for-austria-2004-2016-world-inequality-lab-wp-2020-23/)). |
| WHR | The World Happiness Reports are a partnership of Gallup, the Oxford Wellbeing Research Centre, the UN Sustainable Development Solutions Network, and the WHR’s Editorial Board. The report is produced under the editorial control of the WHR Editorial Board. The Reports reflects a worldwide demand for more attention to happiness and well-being as criteria for government policy. It reviews the state of happiness in the world today and shows how the science of happiness explains personal and national variations in happiness. (https://worldhappiness.report/about/) |
