Shiny Tutorial on Gapminder Data

This is a documentation of the shiny-app created using Gapminder dataset in R

First, check out the final product that we will be attempting to create.

For more check-out my github repo for more content on this project.

So lets begin,

The Default

By default the countries selected in the app are United States and Canada and the quantity to be compared is GDP per capita
Also notice there is a tabulated data space which shows data for the year 2002 by default which can be changed based on the user input
There are two buttons See Github and Attribution which takes the user to my github account or the github account of rebjoh from which this project takes inspiration from

This shiny-app attempts to utilize the following input methods to make it interactive

User inputs

Radio Buttons: to select between Population, Life Expectancy or GDP per capita between the two countries
Select Input : There are 2 select options to select the countries for comparison
Slider Input : Years for comparison can be selected by moving the Slider
Numeric input : The year for which tabulated data has to be displayed can be entered in the input box under the plot based on the years available in the data that is 1952 - 2007 (2002 is default)
Button input : The buttons See Github and Attribution can be pressed to go the links of github accounts for more information

Change some user inputs

I have moved the year slider, changed the year entry for tabulated data
Instead of United States I selected United Kingdom to compare GDP per capita

About the app.R

There are two section of code in app.R file th ui and server
UI defines the looks and interface of the app, themes, layout, inputs etc.
Server does all the heavy lifting of defining inputs and outputs to the UI based on the plots or tabular data

So play around the app
