tidyr is an R package designed to help users clean and organize their data. It provides a set of functions that make it easier to transform data into a tidy format, where each variable is in its own column and each observation is in its own row. This structure simplifies data analysis and visualization. The package includes functions like gather, spread, separate, and unite, which allow users to reshape their datasets efficiently. By using tidyr, researchers and data analysts can streamline their workflow, making it simpler to prepare data for further analysis with other R packages, such as dplyr and ggplot2.
