Tool Summary - R Packages

R Packages
Package/Library	Description	Typical Use Cases
dplyr	Grammar of data manipulation	Filtering, joining, grouping, transforming
ggplot2	Declarative graphics (Grammar of Graphics)	Creating layered plots and charts
tidyr	Data reshaping (“tidy” data)	Pivoting, separating/combining columns
R Markdown	Reproducible reporting (multi-language)	Reports mixing analysis code and narrative

The tidyverse unifies these packages under a common design. As noted, R Markdown ties analysis and narrative, and Posit (RStudio) provides an integrated environment for running code and writing documentation.
