The R language is the de facto standard among statisticians for the development of statistical software, and is widely used for statistical software development and data analysis. R is a modern dialect of S, one of several statistical programming languages designed at Bell Laboratories.
R is much more than a programming language. It’s an interactive suite of software facilities for data manipulation, calculation, and graphical display. R offers a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible. The ability to download and install R packages is a key factor which makes R an excellent language to learn. What else makes R awesome? Here’s a taster.
- It’s free, open source, and available for every major platform. So anyone can repeat your work whatever platform they run.
- A huge set of high quality packages for statistical modelling, machine learning, visualization, and importing and manipulating data.
- Cutting edge tools.
- A suite of operators for calculations on arrays, in particular matrices.
- Deep-seated language support for data analysis. This includes features likes missing values, data frames, and subsetting.
- Powerful tools for communicating your results.
- Produce publication-quality graphs, including mathematical symbols. Dynamic and interactive graphics are available through additional packages. R packages make it easy to produce HTML or PDF, and create interactive websites with Shiny, a sublime R package.
- A strong foundation in functional programming. The ideas of functional programming are well suited to solving many of the challenges of data analysis. R provides a powerful and flexible toolkit which allows you to write concise yet descriptive code.
- RStudio, a powerful integrated development environment.
- Powerful metaprogramming facilities; a fantastic environment for interactive data analysis.
- Connects to high-performance programming languages like C, Fortran, and C++.
- An amazingly vibrant and helpful community.
Packages are the fundamental units of reproducible R code. They include reusable R functions, the documentation that describes how to use them, and sample data. The CRAN package repository hosts over 15,000 packages, and Bioconductor is home to over 1,800 packages.
