In this assignment, I create 3 application for 3 different purposes.

First, Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared.

Second, Drawing plots based on 3 data distribution, normal distribution, exponential distribution, and uniform distribution. There are 2 plotting types, histogram and basic plot.

Third, the last application is an interactive map with 7 wonders of the earth marked. You can mark one by one, or all of it at the same time. Enjoy !

The algorithm for this application is quite simple.

1. Retrieve the height and weight input from user.
2. Calculate the bmi index using bmi formula height / weight squared.
3. Based on the bmi information table, check whether bmi value are in which type.
4. Return the bmi value and the category back to the user.

For this application, this application follows this algorithm.

1. Retrieve user distribution preference.
2. Retreve user desired ammount of data.
3. In the server, create a data according to user desired distribution and plot both histogram and basic plot.
4. Return the plot back to the user.

For this application, the algorithm goes as follows.

1. Create data frame consisting information about the places and coordinates.
2. Take user selected places, and remove information that isn’t selected by user.
3. Using leaflet package, place a mark at user selected place.

Here is the link to the final application.
