About BMI

1. BMI stands for Besal Metabolic Index. It is a measure of fitness, based on height and weight of an adult individual
2. Usually it is measured in Kg/meter-square units (i.e. weight/(length^2)). E.g. if your weight is 70 Kg and height is 1.7 meter, then your BMI is : 24.2215 Kg/meter-square
3. It's range is:- under-weight< 18.5 <= normal < 25 <= over-weight
4. BMI calculation for non-adults is out of scope for this application
   
5. A BMI plot is displayed on the next page (the dataset is inbuilt)

BMI application

1. The BMI application has been developed using cutting-edge technology called "shiny" in Rstudio, using R
2. It has been developed by a leading data-scientist, trained by JHU
3. The application has the following two parts :
   
   1. An UI, which receives inputs and displays output and
      
   2. A Server, that calculates BMI and decides weight-categorization

Using the BMI application

1. The application takes inputs of weight in Kilogram and height in Meter. User will have to confirm that s/he is an adult by selecting Yes/No from a drop-down list.
   
2. Press the "Calculate!" button - the BMI is calculated and displayed.
   
3. To calculate a new BMI, with new inputs, reload the page.
   
4. The server.R does the background work of calculation and generation of the messages. It is not of much importance for the user.
