What is R Programming Language?
In 1993, R was designed as a programming language for activities such as machine learning, statistics, and data analysis. Ross Ihaka and Robert Gentleman created the language, which is open source and used in applications like linear regression, time series analysis, or statistical inference. It runs on operating systems such as Windows, Linux, and macOS with a Command-line interface. R is a modern and widely used tool for data-related work.
Advantages of R Programming
- Open Source: R is an open-source language, which means it’s free to download and use. One can also contribute to code optimization.
- Platform independent: R is cross-platform compatible, making it possible to work on different OSs such as UNIX, Windows, and Mac.
- Data Wrangling: R can transform messy code through its packages, such as read and dplyr.
- Plots and Graphs: R uses ggplot2 and plots to produce graphs with notations and formulas.
- Package Availability: There are many packages in R for creating machine learning and other projects such as data analysis or statistical ones.
Disadvantages of R
- Memory: R uses more memory because all the objects are placed in physical memory. As the program data accumulates over time, this process decelerates.
- Security: Built into web architecture, R lacks basic security that makes it impractical to embed in most cases.
- Difficult to learn: Compared to Python, R is a complex language with many complications, making it quite difficult for a beginner.
- Slow Runtime: R is a language of slow operations. Compared to other languages like MATLAB and Python, it takes a longer time for an output.
- Data Handling: R data handling is cumbersome since all the information needs to be placed in one location. It is not suited for Big Data. But it has an integration that simplifies handling.
What is Python Programming Language?
Developed by Guido van Rossum in 1991, Python is a popular and dynamic programming language. It has been characterized by high readability and brief syntax, which allow programmers to produce shorter code lines. The Python Software Foundation still supports the development of Python, and it’s widely used for different applications.
“Python programming has been an important part of Google since the beginning and remains so as the system grows and evolves. Today, dozens of Google engineers use Python language, and we’re looking for more people with skills in this language. “Â
-Peter Norvig
Director at Google.
Advantages of Python
- Versatility: Python is one of the most flexible languages. It is concise, easy to use, and well-organized. Python is object-oriented, but it transforms itself to include functional characteristics, thus opening a doorway into alternative programming paradigms.
- Open Source: Python can be downloaded easily. It has one of the lively support forums where any individual can contribute to the enhancement of libraries and their functionality.
- Libraries: Numerous libraries for Python should be used in order to perform the major functions associated with data science.
- Productivity: Its ability to integrate and control helps save a considerable amount of time.
- Embeddable: Python codes are embeddable. It is possible to combine Python codes with other programming languages, such as C++.
Disadvantages of Python
- Speed: Being an interpreted language, Python is rather slow compared to many other programming languages.
- Mobile environment: However, Python programs are incompatible with Android and iOS platforms. It is a weak language for developers in such an environment. But it can be used with more work.
- Memory consumption: Python is quite a RAM hog. Slowly, the process becomes slower when many objects are accessed.
- Database Access Layers: However, the database access layers in Python are immature compared to Java Database Connectivity(JDBC) and Open Database Connectivity (ODBC), which makes it a less preferred type of database connectivity.
- Threading: The GIL creates problems in threading or the simultaneous flow of multiple functions into Python.
Python vs. R: Use Cases
The table below shows a comparison of Python vs. R use cases based on prominent applications in various industries.
Python vs. R for Data Science: Data Collection, Exploration, Modeling, and Visualization
Data Collection:
Python:
- Supports various data formats (CSV, JSON) and can import SQL tables.
- Uses the requests library for web-based data collection in web development.
R:
- Imports data from Excel, CSV, and text files and converts files in SPSS or Minitab format to R data frames.
- It is not as versatile as Python for web-based data collection.
Data Exploration:
Python:
- It uses Pandas, a powerful data analysis library, for filtering, sorting, and displaying data.
- Efficiently stores and displays large datasets with multiple features.
R:
- Offers a wide range of options for data exploration and data mining techniques.
- Includes easily accessible statistical tests and algorithms without additional installations.
Data Modeling:
Python:
- Standard libraries like NumPy are for numerical modeling, sci-kit-learn is for machine learning, and SciPy is for scientific computing.
R:
- Relies on external packages, like Tidyverse, for specific modeling evaluations.
- Certain packages make it easy to visualize, manipulate, and report on data.
Data Visualization:
Python:
- It has basic capabilities for data visualizations using libraries like Matplotlib, Pandas, and Seaborn.
R:
- Superior to Python in data visualizations, designed for displaying statistical analysis results.
- It uses a fundamental graphics module for band c charts and ggplot2 for advanced plots like complex scatter plots with regression lines.
How do you choose between Python and R for data analytics?
Choosing between Python and R for data analytics cannot be done as right or wrong since both of these skills are in high demand. It depends on your personal goals and professional background. Consider the following factors as you make your choice:
Popularity:
- Based on the TIOBE, Stack Overflow PYPI, and RedMonk programming language indices, Python is more well-liked in the broader tech community.
