Course Description

Overview of R Programming

R Programming course helps you to learn how to program in R and how to use R for effective data analysis. Things like how to install and configure software which are necessary for statistical programming environment will be learnt discussing generic programming language concepts as they are implemented on a high-level statistical language. This course completes the practical issues in statistical computing which includes programming in R Language, reading data into R, accessing R packages, writing functions in R, debugging, and organizing and commenting in R code.

Duration

3 Days

Prerequisite for R Programming

Students should have knowledge of basic statistics and know the difference between descriptive and inferential statistics. Extensive previous experience in a modern programming language is required.
