Slide 1: Title

  • Course Project: Shiny Application and Reproducible Pitch
  • Application: BMI Calculator Shiny App
  • Author: Your Name

Slide 2: Motivation

  • Many people know their weight and height but do not know their BMI.
  • BMI is a simple index that roughly indicates whether a person is underweight, normal, overweight or obese.
  • The goal of this app is to give users an easy way to calculate BMI using a web interface.

Slide 3: How the App Works

  • User inputs:
    • Weight
    • Height
    • Unit system: Metric (kg, cm) or Imperial (lb, inches)
  • Server logic:
    • Uses the standard BMI formula based on the selected unit system.
  • Output:
    • Numeric BMI value (rounded to two decimals)
    • Corresponding BMI category: Underweight, Normal weight, Overweight, or Obese.

Slide 4: Example R Calculation (evaluated code)

weight_kg <- 70
height_m  <- 1.70
bmi_example <- weight_kg / (height_m ^ 2)
bmi_example
