JOSS Review: Functionality documentation

[wcjochem]

Functionality documentation: Is the core functionality of the software documented to a satisfactory level (e.g., API method documentation)?

I feel the package would benefit from more fully documented functions. While there is a large collection of vignettes, the individual functions have only a minimum template of documentation with argument names and a 1 sentence description. Given that all the functions in the package expect specific formats and types of inputs, I would expect that the type of arguments would be in the documentation. Further expanding the parts of the return values (i.e. more detail than just "list") would also help users.
