1 History and Philosophy

R and Python have different origins and goals that shape their design and features. R was created in the 1990s as a statistical computing environment, based on the earlier S language. It is mainly used by statisticians, researchers, and data scientists who need to perform complex data manipulation, visualization, and modeling. Python, on the other hand, was created in the late 1980s as a general-purpose programming language, with an emphasis on readability, simplicity, and versatility. It is widely used by software developers, web developers, and engineers who need to build applications, automate tasks, and integrate with other systems.

R specializes in statistical data analysis with a rich repository of statistical packages making it a prime choice for statistical modeling. Even though Python offers statistical functions through libraries like SciPy and stats.models but typically falls short of R in terms of statistical package breadth. Python excels in machine learning and AI with libraries like Sklearn, TensorFlow, and PyTorch. While R also offers machine learning tools but Python's ecosystem surpasses it in comprehensiveness. The choice between R and Python for data analysis often depends on the specific needs of the project, personal preferences and the existing infrastructure. Many data analysts and scientists choose to use both languages in their work.

2 Syntax and Style

R and Python have different syntax and style conventions that affect how you write and read code. R has a more functional and expressive syntax, with many operators, symbols, and shortcuts that allow you to write concise and elegant code. However, this can also make R code more difficult to understand and debug, especially for beginners or users of other languages. Python has a more imperative and consistent syntax, with fewer options and rules that enforce a clear and uniform code style. This makes Python code more readable and maintainable, but also more verbose and less flexible.

3 Libraries and Packages

R and Python have both a rich and diverse set of libraries and packages that provide various functions and tools for data analysis. However, they differ in their scope, quality, and availability. R has a more specialized and comprehensive collection of packages for statistical analysis, such as CRAN, tidyverse, and rmarkdown. These packages offer a wide range of methods, models, and formats for data exploration, manipulation, visualization, and communication. Python has a more general and modular collection of packages for data analysis, such as numpy, pandas, matplotlib, and scikit-learn. These packages offer a solid foundation for data processing, computation, plotting, and machine learning, but they may not cover some of the more advanced or niche topics that R does.

I agree with your perspective. However, Comprehensive R Archive Network (CRAN) is rather a package repository and not a package.

4 Community and Support

R and Python have both a large and active community of users and developers who contribute to their growth and improvement. However, they differ in their size, diversity, and culture. R has a smaller and more homogeneous community, mostly composed of academics, statisticians, and data scientists who share a common interest and expertise in data analysis. This makes R more focused and specialized, but also more insular and less adaptable. Python has a larger and more heterogeneous community, composed of various professionals, hobbyists, and learners who use Python for different purposes and domains. This makes Python more versatile and innovative, but also more fragmented and inconsistent.

5 Pros and Cons

R and Python have both pros and cons that depend on your needs, preferences, and goals. R is more suitable for data analysis if you need to perform complex or specialized statistical tasks, use a variety of data formats and outputs, or follow a consistent and coherent workflow. Python is more suitable for data analysis if you need to build or integrate applications, use a simple and clear syntax, or leverage a broader and more dynamic ecosystem. However, there is no definitive answer to which language is better, and you can also use both languages together, depending on the situation and the problem.

R and the survey package deliver a programmable experience to the analysis of complex survey data. Python appears to lack a library such as the survey package and may make R the choice for complex survey analysis.

There exist several tools that can help you translate your code between the two languages and so the switching costs are getting smaller and smaller.
