What is R in Simple Terms?

Developed as a comprehensive open-source data analytic, statistical and visualisation programming environment, R is a powerful open-source programming language used to perform statistical modelling, complex computation and processing of large datasets. The user has complete access to work with include implementing, modifying and extending R programming as a project in any way they wish without having to license R or pay any licensing fees. [1]

Why R is Popular?

A major reason for R’s popularity is its strong statistical capabilities, flexibility, and the large number of active users in the community who support R.

  • Strong Statistical Capabilities: R has many high-level statistical tools to conduct your data analyses (hypothetical testing, regression, probabilities, etc.).
  • Flexibility: R can be used to create and manipulate many types of data for many different uses (i.e., simple calculations to complex models).
  • Machine Learning Support: R can be used in conjunction with Machine Learning algorithms to develop predictive Models; also, you can use these capabilities to analyse advanced data techniques.
  • Extensive Packages: There are thousands of Packages available on CRAN that extend the capabilities of R to efficiently create specialized data manipulation and presentation and develop models.
  • Open-Source Community: R is open-source software, so there are ongoing development and support for it from a Global Community of Users.[2]

Data Analysis with R

With R, data management and analysis can be performed efficiently and with increased insight.

  • Efficient Data Handling: R is a tool that has been created to aid users with the ability to process and utilize large sets of data by making it easy for users to clean, reformat and structure their data more effectively
  • Powerful Packages: Packaging such as dplyr and tidyr provide many additional capabilities for manipulating, filtering, and reformulating the users’ datasets.
  • Time-Saving Analysis: Data preparation and data analysis tasks may be simplified through use of R along with providing the capability to save the user time and produce more quality and meaningful information.[3]

Data Visualization

R provides the ability to clearly and accurately visualize complex data sets.

  • High-Quality Visuals: R provides users with the capability to create extremely high-quality charts, graphs, and dashboards.
  • Powerful Visualization Packages: Tools such as ggplot2 provide users with additional options to customize and beautify their graphical representation of data.
  • Clear Communication of Insights: R’s ability to visualize data in innovative ways makes difficult-to-grasp information easier to digest and allows for more grounded decision-making based on analysis.[4]
