The output of the functions should be "tidy data"

[mpascariu]

In the generated output objects there are too many lists in lists in lists and arrays and matrices. Even for me (the creator of the package) is difficult to read, remember and make sense of the results after a certain point.

A stable version of the package should include only functions and methods that return tidy datasets.

Tidy datasets are easy to manipulate, model and visualize, and have a specific structure: each variable is a column, each observation is a row, and each type of observational unit is a table. (Wickham, 2014)
