convertUnits

This function converts length and area values from one unit to another (e.g., meters to miles, or square yards to acres). Alternatively, it provides the conversion factor for changing one unit to another.

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).
