%description
Provides a collection of helper functions and illustrative datasets to
support learning and teaching of data science with R. The package is
designed as a companion to the book
<https://book-data-science-r.netlify.app>, making key data science
techniques accessible to individuals with minimal coding experience.
Functions include tools for data partitioning, performance evaluation, and
data transformations (e.g., z-score and min-max scaling). The included
datasets are curated to highlight practical applications in data
exploration, modeling, and multivariate analysis. An early inspiration for
the package came from an ancient Persian idiom about "eating the liver,"
symbolizing deep and immersive engagement with knowledge.
