Foundations of R Software (In English language)

By Prof. Shalabh | IIT Kanpur

Learners enrolled: 3351

About the Course :
Any scientific task without the knowledge of software is difficult to complete in the current scenario. R is free software that is capable of mathematical and statistical computing. It has its own programming language, built-in functions, and graphical capabilities to perform any specialized task in mathematics, statistics, and other areas. We intend to learn the fundamentals of R software in this course.

PRE-REQUISITES : Mathematics background up to class 12 is needed. Having some preliminary knowledge will be helpful but not necessarily mandatory.

INTENDED AUDIENCE: UG students of Science and Engineering. Students of humanities with basic mathematical background can also do it. Working professionals in analytics and anyone involved in programming, mathematical and statistical computations, simulations and data analysis can also do it.
INDUSTRY SUPPORT : All industries involved in mathematical and statistical computations, programming and simulations and having R & D set up will use this course.
