The Evolution of R: From S-Inspired Language to Statistical Powerhouse

The Beginner’s Guide to the History of R Programming:

R Programming is basically the dialect of S Programming.


S History:

The S programming language was first developed in the late 1970s by John Chambers and his colleagues at Bell Laboratories. It was initially used for data analysis and graphics, and it served as the basis for the commercial software package S-PLUS, which was released in the early 1990s.

While S-PLUS was popular in the statistical community for many years, it has since been largely replaced by the open-source software environment R, which was inspired by S and developed by some of the same people who worked on S-PLUS.

As for the current version of S, it's not as widely used as R, and there are several different implementations of the S language that are still available today, including:
  • S-PLUS: This is the commercial implementation of S that was developed by TIBCO Software Inc. It is still in use today, although it has been largely supplanted by R in the statistical community.
  • OpenS: This is an open-source implementation of the S language that was developed by members of the R community. It is available under the GPL license and can be downloaded from CRAN (https://cran.r-project.org/web/packages/OpenS/index.html).
  • R's S compatibility mode: R includes a compatibility mode that allows users to run S code within R. This feature was added to R in version 3.4.0 (released in 2017) and is designed to make it easier for users who are transitioning from S to R.

Overall, while the S programming language is no longer as widely used as it once was, its legacy can be seen in the continued use of S-PLUS and in R's compatibility mode.

R History:

R is a programming language and open-source software environment widely used for statistical computing, graphics, and data analysis. It was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, in the mid-1990s. R was initially developed as a free alternative to the commercial software S-Plus, which was popular in the statistical community at the time.

Since its creation, R has grown in popularity and is now one of the most widely used programming languages for data science and statistical analysis. It has a large and active community of developers and users who contribute to its development, support, and documentation.

R is licensed under the GNU General Public License and is available for free download and use from the Comprehensive R Archive Network (CRAN). R also has a number of integrated development environments (IDEs) available, including R Studio, which is a popular choice among R users.

R has a wide range of built-in statistical and graphical functions, and it also supports the use of packages, which can be downloaded from CRAN or other sources. These packages extend R's capabilities and allow users to perform more specialized or complex analyses. There are currently over 18,000 packages available on CRAN alone, covering topics such as machine learning, time series analysis, spatial statistics, and more.

One of the advantages of R is its flexibility and extensibility. Users can easily create custom functions and packages, making it easy to adapt to new research questions or analysis needs. Additionally, R has a robust graphics system that allows for the creation of high-quality visualizations, which are essential for effective communication of results.

Overall, R has become an essential tool for data scientists, statisticians, and researchers across a wide range of fields. Its popularity is due in large part to its flexibility, extensibility, and the large and active community of developers and users who contribute to its ongoing development and support.

Current Version Of R:


The current version of R as of my knowledge cutoff date (September 2021) is R 4.1.1, which was released on July 26, 2021.

R releases new versions on a regular basis, with major releases occurring every year or two, and minor releases (which include bug fixes and small improvements) occurring more frequently. The latest version can always be downloaded from the R Project website (https://www.r-project.org/).

One of the strengths of R is its active development community, which is constantly working to improve and extend the language. This community contributes new packages to CRAN (the Comprehensive R Archive Network), which provides a repository of more than 18,000 R packages that can be easily installed and used with R.

Users are encouraged to keep their installations of R up-to-date to take advantage of the latest features and bug fixes. The R community provides tools to make it easy to upgrade to the latest version, and many users rely on these tools to keep their installations current.

What is Data? And What is Data Science Process?

The Beginner’s Guide to Data & Data Science Process About Data: In our First Video today we talked about Data and how the Cambridge English Dictionary and Wikipedia defines Data, then we looked on few forms of Data that are: Sequencing data   Population census data ( Here  is the US census website and  some tools to help you examine it , but if you aren’t from the US, I urge you to check out your home country’s census bureau (if available) and look at some of the data there!) Electronic medical records (EMR), other large databases Geographic information system (GIS) data (mapping) Image analysis and image extrapolation (A fun example you can play with is the  DeepDream software  that was originally designed to detect faces in an image, but has since moved on to more  artistic  pursuits.) Language and translations Website traffic Personal/Ad data (e.g.: Facebook, Netflix predictions, etc.) These data forms need a lot of preprocessin...

Welcome to the Data Science Specialization using R!

The Beginner’s Guide to the Data Science Specialization using R! In my first video, I introduced the learners to the Data Science Specialization using R. I have covered topics such as data manipulation, data visualization, statistical inference, and machine learning. I have also talked about the importance of using R in data science and the benefits of the Data Science Specialization. You are now ready to dive deeper into the world of data science with R and learn from my expertise. If you haven't watched my first video please find it below: Course Dependency Table: To help my viewers better understand the structure and dependencies of the Data Science Specialization using R, I have provided a course dependency table. This table will show which courses build upon the knowledge learned in previous courses and which courses are prerequisites for others. For the courses, we consider two forms of dependency: Hard dependency: Students will be required to know material from the prerequi...

Mastering R Programming: Best Coding Practices for Readable and Maintainable Code

The Beginner’s Guide to Coding Standards: When it comes to programming, writing code that is easy to read and maintain is just as important as writing code that works. This is especially true in R programming, where it's common to work with large datasets and complex statistical analyses. In this blog post, we'll go over some coding standards that you should follow when writing R code to ensure that your code is easy to read and maintain . Indenting One of the most important coding standards to follow is to use consistent indenting. Indenting makes your code more readable by visually indicating the structure of your code. In R programming, it's common to use two spaces for each level of indentation. For example: if (x > y) {   z <- x + y } else {   z <- x - y } Column Margins Another important coding standard is to use consistent column margins. This means that you should avoid writing code that extends beyond a certain number of characters (often 80 or 100). Th...
