In etc5523-2020/r-package-assessment-prigrecov: Shiny Covid-19 Application Launching

shinyCovidWorld

The goal of shinyCovidWorld package is embedding a Shiny application dashboard about COVID-19 world data exploration and visualization analysis. It makes it launching the application via a function exported by the own package.

This embedded dashboard was previously created as an assessment product while cursing the “ETC5523 - Communicating with Data” unit of Master in Data Science course at Monash University. The shinyCovidWorld package also refactors some parts of the application logic into R functions exported by the package, improving the logic of the shiny application.

As an overview, the main components of this package are one dataset and three functions as follows:

• Data:
  • covidData –> dataset with the COVID-19 cases, deaths, tests, positive rate, and other social and economic variables for each country across the world.
• Functions:
  • launch_app() –> function that runs the shinyCovidWorld application.
  • data_chart() –> function that pre-process this dataset executing some filterings, groupings and summarizings, to be used into plotting codes of this application.
  • text_box() –> function that creates a box with a text instruction inside (the argument function) it in the superior panel of the each navigation tab of the dashboard application.

For more detailed instructions on how to use the package and the functions contained within it access the pkgdown website: shinyCovidWorld.

The Shiny Application - COVID-19 Across The World dashboard

The Shiny App aims to provide an overview analysis of the Novel Coronavirus pandemic across the world using some interactive graphs and tables as visualization tools for this, which were built using the Shiny framework in R.

For more details and information about the content and how the dashboard application works go to the pkgdown website: shinyCovidWorld.

Installation

The development version of this shinyCovidWorld package can be installed from GitHub with:

# install.packages("devtools")
devtools::install_github("etc5523-2020/r-package-assessment-prigrecov")

Usage

It is a basic example of how to run this package:
