What is Tidyr used for?
tidyr is new package that makes it easy to “tidy” your data. Tidy data is data that’s easy to work with: it’s easy to munge (with dplyr), visualise (with ggplot2 or ggvis) and model (with R’s hundreds of modelling packages). The two most important properties of tidy data are: Each column is a variable.

What is the difference between tidyr and reshape2?
Indeed, tidyr ’s aim is data tidying while reshape2 has the wider purpose of data reshaping and aggregating. It follows that tidyr syntax is easier to understand and to work with, but its functionalities are limited. Therefore, we use tidyr to aggregate them.
