datasets

Provides several datasets used throughout the book
"Sampling and Data Analysis Using R: Theory and Practice" by
Islam (2025, ISBN:978-984-35-8644-5).
The datasets support teaching and learning of statistical concepts
such as sampling methods, descriptive analysis, estimation and
basic data handling. These curated data objects allow instructors,
students and researchers to reproduce examples, practice data
manipulation and perform hands-on analysis using R.
