Introduction To R Software

By Prof. Shalabh | IIT Kanpur

Learners enrolled: 3779

Any scientific task without the knowledge of software is difficult to imagine and complete in the current scenario. R is a free software that is capable of handling mathematical and statistical manipulations. It has its own programming language as well as built in functions to perform any specialized task. We intend to learn the basics of R software in this course.

How to learn in this course Lecture 0
