A Brief History of R Programming
In 1993, Statisticians Ross Ihaka and Robert Gentleman at the University of Auckland in New Zealand created the R programming language. They created R to handle data mining and statistical analysis tasks. It originated as an open-source implementation of the programming language S, created in 1976. R was first released in 1995. The R Core Team was created in 1997 and was tasked with continuing to develop this programming language. Then, in 2000, R's initial stable beta version was made available. Three years later, the R Foundation formed, a nonprofit organization devoted to securing support for the R project.
Currently, R is the ranked 11th most-popular coding language available, especially for those who perform data mining. An estimated 2 million people around the globe work with this language. The most recent version of R, R 4.1.2, was released in 2021. As of today, more than 18,000 packages are available for R. Among the most popular is ggplot2, which is used for data visualization. Many of R’s packages make this language faster and easier to use.
Comparable Programming Languages
Another popular programming language that’s commonly compared to R is Python. Similar to R, Python is free and open-source. Both R and Python are widely used in fields such as data analytics, data science, and machine learning. Although these languages bear many similarities, they differ in several important ways:
- R is more commonly used for statistical analysis, whereas Python is often used for general data wrangling tasks.
- Since Python is a multi-purpose language, it provides a largely readable syntax that most people consider easy to learn. On the other hand, R was created by Statisticians and therefore draws from specialized analytics and statistical models. Many Programmers consider R to be a more complex language to learn.
- Python is considered more versatile for tasks such as pulling data from the internet, whereas R is more suited for importing data from CVS and text files, as well as Excel.
- R has more extensive data visualizations than Python. Although Python provides visualization options in popular libraries such as Seaborn and Matplotlib, R was created to help users visualize the results of statistical analyses. R also offers ggplot2, with which users can create advanced plots like scatter plots incorporating regression lines.
- Data modeling is easier in Python since it has various data modeling libraries, such as SciPy and NumPy. Those who wish to perform modeling analysis in R may need to work with packages outside this language’s core functionality.
