R and Python are two popular choices in the fields of machine learning, data science, and analytics. Both of these languages can be used to perform tasks related to data analysis, visualization, and machine learning. In this article, we'll explore R and Python, examining their strengths, weaknesses, and practical use cases to help you make an informed choice.
What is the R programming language?
R was created in the early 1990s by two statisticians, Ross Ihaka and Robert Gentleman. An open-source language specifically designed to analyze and visualize data, R ranks in 7th place on the Popularity of Programming Language (PYPL) index.
Popular R packages
R is well-known for its statistical capabilities with many packages and libraries, making it a popular choice among statisticians. Some of the most popular packages in R are the following:
rvest : Helps to perform web scraping tasks.
Rcrawler : Facilitates web crawling and data extraction.
RSelenium : Provides R bindings for the Selenium Webdriver for browser automation.
readr : Allows users to read data from delimited files such as comma-separated values (CSV) and tab-separated values (TSV).
readxl : Simplifies the import of data from Excel (.xls and .xlsx) files to R with no external dependencies.
sqldf : Compliments the execution of SQL statements on R data frames.
dplyr : Facilitates the performance of data manipulation.
ggplot2 : Produces elegant data visualizations for data professionals working in R.
caret : Attempts to simplify the process of developing predictive ML models.
shiny : Makes it simple to create interactive web apps.
All these mentioned, plus another 19,000+ packages, are available on Rs Comprehensive R Archive Network (CRAN). You can install them using the install.packages("package_name") command.
What is the Python programming language?
Created in the late 1980s by Guido van Rossum, Python is an open-source, general-purpose language that ranks 1st place on the Popularity of Programming Language (PYPL) index.
Popular Python packages
Python wasnt initially intended for data science, but its simplicity, and readability with a wide range of relevant libraries made it popular in the data science community. Here are some of the most popular packages in Python:
Requests : Helps in sending HTTP requests to a server in Python.
BeautifulSoup : Provides an ability to parse HTML/XML documents.
Scrapy : Offers flexible web scraping, crawling, and data extraction features to Python users.
Selenium : Provides browser automation and a testing ecosystem.
pandas : Helps in importing data (supports files with various formats such as .csv, .tsv, etc.) and data manipulation.
Matplotlib : Provides standard data visualizations.
scikit-learn : Offers practically all ML algorithms in Python.
seaborn : Provides data visualizations with customized themes and colors.
PyCaret : Helps to simplify and automate ML programs.
Streamlit : Makes it faster to build data apps in pure Python.
All these and another 480,000+ packages are available on Pythons Python Package Index (PYPI). You can install them using the command: python3 -m pip install "package_name" or pip3 install "package_name".
