Introduction : This Course is first in the series of our Data Science courses. It's aimed at providing a strong foundation in R-programming for Data Science enthusiasts. R-Statistics is the most widely used tool in the area of Data Analysis (used extensively in both Industry and Research) and so, is the base for all of our courses. This course is meant for people planning to start a career in the Data Science field and also for those who know the basics, but lack practice and grip over the subject.

NOTE : Each section is concluded with hands-on exercises (on inbuilt dataset and also by reading data from a file/database)

Section-B (Day-3):

On day-3, we do a complete Data Analysis Project using R and try to figure out useful patterns for a real case (we have got data from a Clothing Store Chain, which has multiple stores across the city). So, towards the end, participants will do certain analysis on this data set and see the patterns using R graphics and charting tools.
