R: A Statistical Analysis and Computing Programming Language

R is a user-friendly, free programming language used for statistical analysis and computing. It offers various statistical techniques including linear and nonlinear modeling, statistical testing, and clustering. One of R’s significant advantages is the ease of creating mathematical notations and equations for visualization.

Developed by Ross Ihaka and Robert Gentleman in 1993, R works on various operating systems like UNIX, Windows and macOS. Users can build user-specific functions to extend R’s functionality. Big companies like Google, Meta, Airbnb, and Uber currently manage various R programming endeavors. Moreover, R allows for connecting C and C++ routines at runtime for complex tasks, and through packages, it extends to additional languages like C++.

Applications of the R Programming Language

R is a popular programming language in real-world applications for the following reasons:

  • Open source: R is an open-source language that allows users to improve the source code.
  • Platform independent: R can run on various operating systems like Windows, UNIX, and Mac.
  • Data manipulation: The packages readr and dplyr help R to convert complex code into organized forms.
  • Plotting: R enables users to create visually appealing graphs through ggplot and plotly.
  • Packages: R has numerous packages devoted to machine learning, data analysis, and statistical projects.

Sentiment Analysis in R

Sentiment analysis involves evaluating words to determine if they express positive or negative opinions. This type of categorization can be binary (optimistic or pessimistic) or multiple (happy, angry, sad, disgusted). Our project in R uses the Janeausten package dataset and general-purpose lexicons like AFINN, bing, and Loughran. We present the results using a word cloud after performing an inner join. Check out the source code on GitHub: https://github.com/yashspr/sentiment_analysis_ml_part.

Uber Data Analysis Using R Packages

Utilizing data visualization, companies can comprehend complex datasets and make informed decisions. This Uber data analysis project utilizes R packages like ggplot2 to extract insights from user data to accurately predict clients who will take Uber trips and rides.

The analysis looks at several criteria, including the number of journeys and travels made per day and month, respectively. This study enables Uber to determine daily average passenger count, peak hours with the most available commuters, days with the highest number of identified trips, and more.

Movie Recommendation Engine using R

This project aims to create a recommendation system for movies using a collaborative filter based on items. The system will utilize user preferences and browser history to suggest movies and videos. The MovieLens dataset was used, where 105339 ratings were given to 10329 movies from the ratings.csv and movies.csv files.

By implementing this project, you can gain practical experience in Data Science, R programming, and Machine Learning. Websites like YouTube and Netflix use similar recommendation engines to filter the user’s past search results and suggest suitable content. You can access the source code of this project on Github [https://github.com/Rpita623/Movie-Recommendation-System-using-R_Project].

Credit Card Fraud Detection

Using R programming, we can create a fraud detection application that identifies fraudulent credit card transactions. A variety of machine learning methods, including decision trees, regressions, artificial neural networks, and others, are used in this project. The system is based on a dataset of card transactions that includes both fraudulent and legitimate transactions. The steps in this project include importing, examining, altering, and organizing transaction data, modeling, fitting, and implementing the algorithm. Check out the source code here: [https://github.com/Rpita623/Detecting-Credit-Card-Fraud]

Wine Quality Prediction

We can use predictive modeling to enhance wine quality. In this study, we will use the “red wine” dataset to determine the wine’s quality and learn more about its chemical qualities.

Our goal is to forecast wine quality using input factors, identify the wines with outstanding characteristics, and explore the unique relationships between the dataset’s data. We will also practice data visualization, data exploration, and regression models through this project.

CUSTOMER SEGMENTATION

Customer segmentation is a popular Data Science project which involves unsupervised learning. Businesses use clustering to recognize customer groups and reach out to a wider user base. To market to each group efficiently, they classify individuals based on shared characteristics such as gender, age, hobbies, and buying habits.

K-means clustering is employed to visualize the gender and age distribution. After that, their yearly income and expenditure habits are analyzed.

Speech Emotion Recognition

Speech is an essential means of expressing ourselves that involves several emotions, including quietness, anger, happiness, and passion. By analyzing the emotions in speech, we can tailor our services and products to meet the needs of specific individuals. The primary objective of this project is to identify and extract emotions from various audio files that comprise human speech.

Product Bundle Identification

Product bundling is a marketing strategy that combines several items and sells them as a single package at a discounted price to attract customers. In this R project, subjective segmentation and clustering techniques are used to group products together to offer great deals, like the Pizza Hut meal deal. The dataset used is the “weekly sales transaction” data that contains purchase quantities of various items. In this project, time series clustering is used to identify product bundles and compared to traditional Market Basket Analysis. You can find the source code at [https://github.com/onkarM17/Using-Sales-data-to-iIdentifying-Product-Bundles-in-R].

Voice Gender Recognition

This project focuses on identifying the gender of a voice by analyzing auditory data such as pitch and frequency. Machine learning algorithms are employed to categorize the voice as male or female. A dataset of 3,168 recorded speech samples from both genders was used to train the model, which was pre-processed in R for acoustic analysis. The trained model uses AI/ML algorithms to learn gender-specific features for accurate categorization. Check out the project’s source code at [https://github.com/primaryobjects/voice-gender].

Fake News Detection

It is easy to spread false information on the internet, also known as fake news, which can cause harm to individuals, fear and even violence. In order to combat this, it is essential to identify the credibility of the information. This data science project focuses on developing an automated fake news detection system, with a focus on real-world politics and social media.

The objective of the project is to build a classifier to identify whether a political statement from the 2016 US elections is real or fake news.
