R Programming language and environment designed for statistical computing and data analysis. Here are some key concepts:
- Vectorization: R is particularly strong in vectorization, allowing operations on entire vectors or matrices at once, making it efficient for statistical computations.
- Data Frames: R operates with data frames, a type of table that makes it easy to handle and analyze structured data.
- Functions and Packages: R has a vast ecosystem of packages that extend its functionality. Functions are a fundamental part of R, and users can create their own functions as well.
- Graphics and Visualization: R provides powerful tools for data visualization, making it easier to explore and understand data through various graphical representations.
History of R Programming
R has its roots in the S programming language, developed at Bell Laboratories by John Chambers and his colleagues in the 1970s. Ross Ihaka and Robert Gentleman created R at the University of Auckland, New Zealand, in the early 1990s. It has since evolved into a widely-used language for statistical computing and data analysis.
Features of R Programming
- Open Source: R is an open-source language, meaning that its source code is freely available, and users can modify and distribute it.
- Statistical Analysis: R is specifically designed for statistical computing and analysis, offering a rich set of statistical functions.
- Data Manipulation: With packages like dplyr and tidyr, R makes it easy to manipulate and clean data efficiently.
- Community Support: R has a large and active user community, contributing to its extensive range of packages and resources.
