Data Science with R Tutorial

Last Updated : 23 Feb, 2026

Data Science combines statistics, programming and domain knowledge to extract insights from data. R is a widely used language for statistical computing, data analysis and visualization. It provides rich libraries that simplify data manipulation, modeling and reporting.

  • Use popular R libraries like dplyr, ggplot2 and tidyr for data cleaning and visualization.
  • Perform statistical analysis and build models using packages such as caret and randomForest.
  • Work with real datasets in RStudio to analyze, visualize and interpret results efficiently.

Installation of R

This section explains how to install R and RStudio and understand the basic R environment.

Foundations of R

This section covers the fundamental concepts of R programming, including syntax, variables, data types, operators and data structures that form the base for data analysis

Data Preprocessing in R

In this section, we will explore how to preprocess data in R by handling missing values, converting data types and preparing datasets for analysis.

Data Visualization in R

This section explains how to create meaningful visualizations to explore and present data. It covers ggplot2 for static plots and Shiny and Plotly for interactive visualizations.

Data Analysis with R

This section covers techniques for exploring datasets and extracting insights. It includes exploratory data analysis, data aggregation, feature scaling and encoding categorical variables.

Statistical Analysis in R
