As data science continues to grow and become an essential part of many industries, the need for effective tools in analyzing and manipulating data has also increased. Today, R and Python are two of the most widely used data science tools. These two tools have been the focus of many debates on which one is the best. Comparing R and Python in data science reveals that each tool has its strengths and weaknesses.
Before we delve deeper into the comparison of R and Python in data science, let us first discuss what they are.
What Is R?
R is a programming language developed mainly for statistical computing and graphics representation. R language has a wide array of packages dedicated to data science functions, and they are mostly free and open source. R is particularly popular in the statistical industry, which is why it has some significant advantages for data scientists and other researchers.
What Is Python?
Python is another programming language that is generally used for general-purpose programming. However, Python has revolutionized data science in recent years with packages such as Pandas, NumPy, Matplotlib, and Scikit-learn.
Comparison of R and Python in Data Science
Here is a comparison of R and Python using various data science aspects.
- Popularity
One way to compare R and Python in data science is by popularity. According to recent surveys, Python is a more popular language than R. In the 2020 Stack Overflow survey, Python ranked as the third most popular programming language globally, with R ranking at 8th place. Python’s popularity in data science is relatively new and tends to persist, while R has had an established fan-base for years.
- Ease of Use
Both R and Python are relatively easy to learn, but Python comes with a relatively simple and straightforward syntax. Python syntax is typically very similar to that of a regular, everyday language, making it easier to understand and learn. On the other hand, R’s syntax varies, depending on the package you’re using, and might feel more complicated than Python should you go and use several of them. What’s more, for some people, the R package interface is not comfortable since it’s so different from other programming languages.
- Data Manipulation
When it comes to data manipulation, both R and Python compare favorably. R tends to be more reliable and flexible in terms of data storage options and working with the data. It’s packed with data management and analysis features, with more advantages for data visualizations tasks. However, Python has incorporated packages such as NumPy, Pandas, and Matplotlib in recent years, rendering it powerful enough for anything that R can do. Additionally, Python is often more efficient and quicker than R for large data sets that don’t fit into the memory.
- Machine Learning and Deep Learning
Python has a wide range of open-source libraries, such as TensorFlow and Keras, that make it a natural choice for machine learning and deep learning. Python packages like scikit-learn have defined the standard in performing common mathematical and statistical tasks in machine learning. On the other hand, R has libraries and packages like caret and random forest, which are applied in random forests and several machine learning models. However, it falls short on deep learning libraries where Python’s TensorFlow dominates.
- Graphical Representation
When it comes to graphical representation, R beats Python. R has a more sophisticated and developed library of data visualization packages compared to Python. For instance, ggplot2 is a powerful package in R, while Python’s visualization library, Matplotlib, is not as advanced.
- Community Support
Both Python and R have enthusiastic and active users, contributing to an amazing set of packages, as well as mailing lists, blogs, StackOverflow questions and answers, etc. Python has a more extended community with over 1 million libraries on the PyPI (Python Package Index) directory, and Python developers can join and receive help from communities like Google Groups, Reddit, and more. Alternatively, R is more distributed, with focused communities, primarily based on packages and course materials.
Conclusion
In conclusion, both R and Python are great tools for Data Science. It all comes down to the user’s preference, field of application, and scope of work. When working on databases that might be significant in storage, Python will be the tool of choice while working on statistics that require data visualization; R is the best choice. Whether you use R or Python, as a data scientist, it takes years of unending learning and hard work to become an expert in either.
