R language

  • What Is R? ... and for what? Getting starting

    What Is R? Who Uses R and Why?R is a computer program that lets you analyze data. By “analyze” we mean, first, read the data into the program and then operate on it – drawing graphs and charts, manipulating values, fitting statistical models, and so on. R is both a statistical “environment” and also a programming language, and it is very widely used both in commercial and academic settings. R is free and open-source and runs on Windows, Apple, and Linux operating systems. It is maintained by a group of volunteers who release bug fixes and new features regularly.

  • Why Use R for Business Case Analysis?

    Using R language for Business Case AnalysisBusiness case analyses that are typically developed in spreadsheets are fraught with a lack of transparency and prone to propagating significant coding errors. The R programming language provides a better alternative for creating clear and minimal-error analysis.

    Even if you are new to R, you most likely have noticed that R is used almost exclusively for statistical analysis, as it’s described by The R Project for Statistical Computing. Most people who use R do not frequently employ it for the type of inquiry that business case analysts use spreadsheets to select projects to implement, make capital allocation decisions, or justify strategic pursuits. The statistical analysis from R might inform those decisions, but most business case analysts don’t employ R for those types of activities.
