R is available on the CRAN website (Comprehensive R Archive Network]. Can contain bugs and errors: packages that are widely used are probably correct, niche packages can contain errors, there is no central team assessing the quality of the code.Open source: documentation can be poor or written by/for experts.Open source: many people contribute thus consistency can be low.Difficult if you don’t have any programming experience.It can struggle with extremely large datasets.Supports all statistical analyses: from basic to very complex.A lot of freedom: graphs can be produced to your own taste.It can deal with very large datasets (compared to Excel).An enormous variety of statistical analyses are available and R allows you to produce graphs exactly as you want them with publication quality. It is not easy to learn the language if you haven’t done any programming before but it is worth taking the time as it can be a very useful tool. The R project is largely an academic endeavor, and most of the contributors are statisticians, hence the sometimes incomprehensible documentation.Īs a computer language it was created to allow manipulation of data, statistical analysis and visualization. There is no company regulating R as a product. This statement comes up on the screen every time you start R. This is good for the user, although there are some disadvantages: R comes with ABSOLUTELY NO WARRANTY. The development of R is done under the philosophy that software should be free of charge. This course is part of several tracks, including Data Analyst with R, Data Scientist with R, and R Programming, all of which can help you develop your knowledge.As a project, R is part of the GNU free software project. These sought-after skills can help you progress in your career and set you up for further learning. Finally, you’ll explore how to work with R data frames and lists.īy the time you’ve completed our Introduction to R course, you’ll be able to use R for your own data analysis. You’ll also examine how R uses factors to store categorical data. Next, you’ll learn how to work with matrices in R, learning how to create them, and perform calculations with them. Once you’ve had a chance to practice, you’ll move on to creating vectors and try out your new R skills on a data set based on betting in Las Vegas. You’ll get started with basic operations, like using the console as a calculator and understanding basic data types in R. You’ll gain useful coding skills and be ready to start your own data analysis in R. This introduction to R course covers the basics of this open source language, including vectors, factors, lists, and data frames. R's ability to handle complex analyses such as machine learning, financial modeling, and more makes it a valuable asset for a wide range of data-related tasks. R programming language is a useful tool for data scientists, analysts, and statisticians, especially those working in academic settings.
