usefun: A Collection of Useful Functions by John

A set of general functions that I have used in various projects and in other R packages. They support some miscellaneous operations on data frames, matrices and vectors like adding a row on a ternary (3-value) data.frame based on positive and negative vector-indicators, rearranging a list of data.frames by rownames, pruning rows or columns of a data.frame that contain only one specific value given by the user, pruning and reordering a vector according to the common elements between its names and elements of another given vector, finding the non-common elements between two vectors (outer-section), normalization of a vector, matrix or data.frame's numeric values in a specified range, pretty printing of vector names and values in an R Markdown document. Also included is a function that returns the statistics needed for plotting a ROC curve.
