BMI Calculator Using Shiny App

Build an application to demonstrate following skill :

• use of various widgets of 'shiny' tool
• understanding of the process of publishing application in shiny
• interface with R using embeded R code

The application developed is a BMI calculator. This application takes height in CM and weight in KG of person as input and displays the BMI of the user. Following code demostrates the calculation part.

height<- 150
weight <- 56

bmi<- weight/(height*0.01 * height * 0.01)  

bmi

It includes 4 widgets:

• numericInput - A field to enter numbers, in this case - the height (in CM) and weight(KG)
• actionButton - An Action Button, in this case to provide non-reactive reactivity to refresh and calculate value of BMI.
• Textfield - to display entered value by user.
• TabPanel - to show result and documentation on separate TAB

• Try out the application on the RStudio shinyapps.io website: https://rmaster.shinyapps.io/BMICalculator/
• To see the code for the application, visit github website: https://github.com/RMaster/Data-Product
• Useful files in repo:
  • server.R
  • ui.R
• To execute the application and see the code in action, use: runApp(displayMode = 'showcase')
