The "ISLR" package provides datasets used in the book "An Introduction to Statistical Learning with Applications in R" by Gareth James, Daniela Witten, Trevor Hastie, and Rob Tibshirani. It includes data for various statistical learning applications, such as regression, classification, and clustering. The package contains datasets like Auto, Caravan, Carseats, College, Credit, Default, Hitters, Khan, NCI60, OJ, Portfolio, Smarket, Wage, and Weekly. Each dataset is described with its variables, source, and usage examples. The Auto dataset contains information on 392 vehicles, including gas mileage, horsepower, and weight. The Caravan dataset includes 5822 customer records for insurance policy purchases. The Carseats dataset contains sales data for car seats at 400 stores. The College dataset includes statistics for US colleges. The Credit dataset contains information on 10,000 customers for credit card default prediction. The Default dataset is similar to Credit but focuses on default prediction. The Hitters dataset contains baseball player statistics. The Khan dataset includes gene expression data for cancer types. The NCI60 dataset contains microarray data for cancer cell lines. The OJ dataset contains orange juice purchase data. The Portfolio dataset is a simulated dataset for portfolio optimization. The Smarket dataset contains stock market data. The Wage dataset includes wage information for 3000 workers. The Weekly dataset contains weekly stock market returns. All datasets are sourced from various studies and are used for statistical learning examples in the book.The "ISLR" package provides datasets used in the book "An Introduction to Statistical Learning with Applications in R" by Gareth James, Daniela Witten, Trevor Hastie, and Rob Tibshirani.
