Python vs R: Realistic Comparison
Post-COVID, we are moving to a new technological frontier led by data science, artificial intelligence, and machine learning. These three front liners of the modern technology evolution play a significant role in bringing so many things into a reality that we seldom imagined. If you are aware of these technological evolutions, then you would be mindful that Python vs R for data science is a matter of interest and feud for many.
Both languages have many similarities and dissimilarities, many advantages and disadvantages, and strengths and weaknesses. Yet, you need clarification when it comes to choosing one between them. Let’s differentiate Python vs R on a more comprehensive level.
Python: According to The Importance Of Being Earnest (TOIBE) index, Python scaled the highest position from the day it was released. It reached No-1 in December 2022 with an overall rating of 16.36%, representing an increase in demand of 2.78% over the last year. Besides, according to Stack Overflow Developer Survey, Python became the third most popular language.
R: According to the Same TIOBE report, R is not as popular as Python, yet it does its career best by reaching No-13. R received a 1.04% rating; but slipped in demand and popularity by –0.21%. It is interesting to note that R was at No-8 in the year 2020, but it is decreasing in popularity year-on-year.
🟠 Speed and Performance
Python: As a high-level programming language, Python makes a perfect choice for building critical applications quickly. Although Python has earned more praise than R, they differ minutely in execution time and speed.
R: Conversely, R is a complex language where you need to write lengthy code even for simpler processes, increasing the development time. Similar to Python, even R is capable to handle larger and more robust data operations.
Both languages are slower than compiled programming languages like C or C++. Yet, they overcome this issue by allowing specific C or C++-based extensions to achieve the speed matching to the C language.
🟠 Libraries and Packages
Python: Python libraries and packages are collections of related code modules used repeatedly by different programs. Python libraries such as Matplotlib, Seaborn, and Plotly are used for plotting numerical data (Visualization). The Pandas library provides flexible high-level data structures and tools that are useful in data analysis, cleaning, and manipulation. The NumPy library doubles up as an ML tool that supports multidimensional data and large matrices. It has in-built mathematical functions for computations.
R: On the contrary, R is also equipped with various libraries and packages, like the ggplot2 library, often useful for data visualization, and the shiny package, widely utilized for building interactive web applications. Additionally, the RCrawler package is well known for web scrapping and domain-based web crawling, whereas tidyverse is excellent for data manipulation. CRAN is another alternative package for R, which is less standardized with a varied API and usage, making it hard to learn and combine.
R vs Python for data science is not a subject of debate, as they both offer thousands of packages and libraries you can use for free in your project. Python is an excellent choice for building full-fledged applications, and R would be a better option if you want to manipulate data from popular data stores. Suppose you can create, use, destroy, and manipulate various environments with multiple or different packages installed. In that case, archiving similar performance from R is a challenge due to the limitations of its packages.
🟠 Graphics and Visualization
Python: Several libraries in Python have been made available recently to create beautiful, stunning, and engaging data visualization and graphics. Libraries such as Matplotlib, Plotly, Seaborn, GGplot, Altair, Bokeh, and many more come with unique advantages to create stunning graphics and visualizations. You can use these libraries to create line charts, bar graphs, scatter plots, heat maps, and similar visualizations.
R: You must write a few lines of code in R to create beautiful and visually stunning graphics and visualizations. There are a series of packages available in R like Plotly, ggplot2, tidyquant, taucharts, ggiraph, geofacet, and many more for data visualization.
Some feel that visualization in R is more straightforward than extensive libraries in Python, rather than helping make data visualization a complex process. However, Seaborn and Matplotlib have debunked this myth, and Seaborn enables you to create stunning visualizations by writing few lines of code than what you will write in ggplot2.
🟠 Learning Curve
Python: Python has a smoother learning curve due to its simple syntax, which is similar to English. Many programmers find it easier to code in Python due to the less tie consumption in writing the code.
R: Many feel R has a longer or more complex learning curve. Due to the non-standardized code, R is a little difficult to master. Even some experienced programmers think that R could be more convenient, which has often made them awkward.
Although R is difficult for beginners and entry-level developers, statisticians and people with prior experience in statistics find it easier to understand. R developers often feel that Python focuses on less essential things. Yet, go with R, if you are looking for an easy and time-efficient programming language.
