The correct answer is D. tidyr is a reframing of reshape2, reshape5, and dplyr designed to accompany the tidy data framework.
tidyr is a package for tidying data. It provides a set of functions for reshaping data, converting between different data structures, and splitting and merging data. tidyr is designed to be used with the tidy data framework, which is a way of organizing data that makes it easy to work with.
reshape2 is a package for reshaping data. It provides a set of functions for converting between different data structures, such as wide and long data. reshape2 is designed to be used with the tidy data framework.
reshape5 is a package for reshaping data. It provides a set of functions for converting between different data structures, such as wide and long data. reshape5 is designed to be used with the tidy data framework.
dplyr is a package for data wrangling. It provides a set of functions for selecting, transforming, and joining data. dplyr is designed to be used with the tidy data framework.
All of these packages are useful for working with data. However, tidyr is the most recent and up-to-date package. It also provides a more consistent interface for reshaping data.
