rotateMatrix

This function rotates the values in a matrix by a user-specified number of degrees. In almost all cases some values will fall outside the matrix so they will be discarded. Cells that have no rotated values will become <code>NA</code>. Only square matrices can be accommodated. In some cases a rotation will cause cells to have no assigned value because no original values fall within them. In these instances the mean value of surrounding cells is assigned to the cells with missing values. If the angle of rotation is too small then no rotation will occur.

An assortment of helper functions for managing data (e.g.,
rotating values in matrices by a user-defined angle, switching from
row- to column-indexing), dates (e.g., intuiting year from messy date
strings), handling missing values (e.g., removing elements/rows across
multiple vectors or matrices if any have an NA), text (e.g.,
flushing reports to the console in real-time); and combining data frames
with different schema (copying, filling, or concatenating columns or
applying functions before combining).
