A Collection of Handy, Useful Functions

A set of little functions that have been found useful to do little odds and ends such as plotting the results of K-means clustering, substituting special text characters, viewing parts of a data.frame, constructing formulas from text and building design and response matrices.

Useful is a collection of handy functions that I have collected over the years but do not have a place in an particular package. More are added as I build.

Since useful is so varied I will, over time, add example use cases to this README.
