#NUS summer course Computational Thinking: Algorithms for Big Data Community Detection: Basic ###Solution provided by Dex

Most basic usage of R. A lot of credit goes to @akrun since he answered my question in stackoverflow. See the [link] (http://stackoverflow.com/questions/38428111/count-unique-values-of-multiple-columns-in-r)

Since the guide for assignment2 is already too detailed, there is nothing more to be done for this assignment.

In final project, I also put my presentation powerpoint in. This module is really simple and relaxing, few things to learn really.
