npartfull: Manning's n for Closed Conduits Flowing Partly Full (Chow, 1959)
nmetalpipe: Manning's n for Corrugated Metal Pipe (AISI, 1980)
r* (3 data sets): Nominal Interest Rate Tables (Engineering Economics)
i* (19 data sets): Effective Interest Rate Tables (Engineering Economics)
pres_elect1: US Presidential Elections (Wikipedia)
