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).
