8. 1. Introduction

9. What is R? R is a language and environment for statistical computing and graphics. Environment = planned and coherent system of flexible tools (“An Introduction to R” by R Core Team). R can be used for: data manipulation, data analysis, creating graphs, designing and running computer simulations. R is extended by thousands of packages described in “Task Views” at CRAN (The Comprehensive R Archive Network): https://cran.r-project.org/web/views/https://cran.r-project.org/web/views/
