Pros and Cons of R Programming Language

R is a programming language that is open source and free to use, which makes it a popular choice for data visualization and quantitative analysis. R has been around since 1992, and it offers a vast ecosystem that includes intricate models and eye-catching data reporting capabilities. RStudio, which is an Integrated Development Environment (IDE), is often used in conjunction with R to provide an easier way to perform statistical analysis, visualization, and reporting. Additionally, Shiny allows developers to immediately utilize and actively deploy R programs on the web. Consequently, R is now one of the most commonly used statistical languages in the business domain.


  • R’s expansive community is one of its key strengths, and it provides assistance through mailing groups, user-contributed documentation, and a very active Stack Overflow group. 
  • Another advantage of R is CRAN, a large repository of curated R packages to which anyone can freely contribute. These packages contain a set of R functions and data that make it easy to get started with the latest techniques available. Currently, CRAN contains around 12,000 packages. 
  • Due to its extensive library, R is the preferred choice for statistical analysis, particularly for specialist analytical tasks.
  • R offers a wide range of libraries and tools for several stages of data analysis, including data cleansing and preparation, creating visual representations, and implementing machine learning and deep learning algorithms.


  • R shares its origin with an older programming language “S,” which means its base package lacks support for dynamic or 3D graphics. However, common packages like Ggplot2 and Plotly allow for the creation of dynamic, 3D, and animated graphics.
  • R stores objects in physical memory, which differs from other languages like Python, and utilizes more memory. It also requires the entire data to be in memory, making it less ideal for big data. However, data management packages and integration with Hadoop can cover this limitation.
  • R lacks basic security, which limits its embedding into web applications, unlike other languages like Python.
  • It has a steep learning curve, making it difficult for people without prior programming experience to learn.
  • This programming language is slower than other languages like MATLAB and Python.

R Vs Python for Data Science- A Detailed Comparison

Collection of Data

Python is a versatile programming language that can handle a wide range of data types, making it ideal for data analysis. It can read and write data in different file formats, including CSV and JSON files. It can also import data directly from SQL tables into Python scripts. Furthermore, the Python requests package makes it simple to gather data from the web and use it to generate datasets in web development. In contrast, R was primarily for data analysts who need to integrate data from Excel, CSV, and text files.

Learning Curve

Python has a smoother and more linear learning curve than R, making it easier to learn for beginners. Python’s syntax is similar to English, and its code is more readable and understandable. R, on the other hand, is more challenging at the beginning, with a steeper learning curve.

Data Visualization

While Python does not have a built-in visualization package, you can use the Matplotlib module to create basic graphs and charts. The Seaborn module, on the other hand, allows you to create more visually appealing and informative statistical visuals in Python. R, on the other hand, primarily showed the findings of statistical analysis, with the fundamental graphics module making it easy to create basic charts and plots.

Use Base
