Title: R Programming Language Author: Kriko Published: Jun 8, 2023 Last modified: Jul 7, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. R Letter # R Programming Language **R** is an open-source programming language and software environment widely used for statistical computing, [data analysis](https://kriko.io/services/data-analysis-insight) and graphics. It was initially developed in the early 1990s by Ross Ihaka and Robert Gentleman at the University of Auckland. Today, its development is supported by the R Core Team and contributors from around the world. R is frequently used by statisticians, researchers, [data](https://kriko.io/services/data-analysis-insight) analysts and [data](https://kriko.io/services/data-analysis-insight) scientists. It supports a broad range of methods, including linear and nonlinear modelling, classification, clustering, time-series analysis and machine learning. It is also particularly effective for **[data](https://kriko.io/services/data-analysis-insight) visualisation**, statistical analysis and [data](https://kriko.io/services/data-analysis-insight) manipulation. One of R's main strengths is its extensive ecosystem of libraries and packages. Users can expand the language's capabilities by installing packages designed for specific analytical methods, industries and research areas. Many of these packages are distributed through the Comprehensive R Archive Network, commonly known as CRAN. R can be used through a command-line interface as well as integrated development environments, or IDEs. These environments make it easier to write, organise, test and debug R code while managing analytical projects more efficiently. A typical [data analysis](https://kriko.io/services/data-analysis-insight) workflow in R may include the following stages: **[Data](https://kriko.io/services/data-analysis-insight) Import:** [Data](https://kriko.io/services/data-analysis-insight) is collected from sources such as databases, spreadsheets, files, APIs or analytical platforms and transferred into the R environment. **[Data](https://kriko.io/services/data-analysis-insight) Transformation:** Raw [data](https://kriko.io/services/data-analysis-insight) is cleaned, reorganised and converted into a structure suitable for analysis. This may include filtering records, correcting values, combining datasets and creating new variables. **[Data](https://kriko.io/services/data-analysis-insight) Exploration:** The [data](https://kriko.io/services/data-analysis-insight) is examined to identify patterns, relationships, anomalies and possible areas of interest. Visualisations and summary statistics are frequently used during this stage. **Statistical Modelling:** Appropriate statistical or machine learning models are selected, developed and evaluated according to the analytical objective. **Communication:** Findings are presented through charts, reports, dashboards or reproducible documents so that insights can be understood and used by relevant stakeholders. R supports **reproducible analysis** by allowing code, calculations, visualisations and analytical outputs to be documented within the same workflow. This makes it easier to review, repeat and share analytical processes. With its extensive package ecosystem, strong statistical capabilities and flexible visualisation tools, R remains an important environment for academic research, data science and advanced analytics. The official R Project describes it as a language and environment developed specifically for **statistical computing** and graphics. ## Discover it in the dictionary ### Breadcrumb Breadcrumbs, also known as breadcrumb navigation, are a secondary navigation system that helps users understand where the current page sits within a website's hierarchy.… ### Cost Per Click (CPC) CPC stands for "Cost Per Click" and refers to the cost per click in digital advertising.
