internal

Building modeling packages is hard. A large amount
of effort generally goes into providing an implementation for a new
method that is efficient, fast, and correct, but often less emphasis
is put on the user interface. A good interface requires specialized
knowledge about S3 methods and formulas, which the average package
developer might not have.  The goal of 'hardhat' is to reduce the
burden around building new modeling packages by providing
functionality for preprocessing, predicting, and validating input.
