tidyr is an R package from the tidyverse that provides tools for reshaping messy data into tidy form, including pivoting between long and wide formats, rectangling nested lists, and handling missing values. It is a core data-wrangling dependency widely used in R data analysis workflows.

Use cases

• reshape a wide dataset into long format for plotting
• convert long data to wide with pivot_wider
• flatten nested JSON-like lists into tidy tibbles
• fill in missing values in a time series
• split a single character column into multiple columns
• make implicit missing values explicit in grouped data

When to choose

• you work in R and need to reshape or clean data frames
• you use the tidyverse and want consistent tidy-data tooling
• you need to unnest or rectangle deeply nested list data

When to avoid

• you work outside R
• you need high-performance reshaping of very large datasets better served by data.table
• you only need SQL-style joins or aggregation rather than reshaping
