iemisc: Irucka Embry's miscellaneous functions

Description

iemisc provides many useful functions. There are statistical analysis [RMS, approximate and relative error, maximum mean relative error (MAXRE), and mean relative error (MRE), coefficient of variation (CV), range, harmonic mean, geometric mean], engineering economics (benefit-cost, future value, present value, annual value, gradients, interest, periods, etc.), geometry (polygon area, sphere volume, and right triangle validation), civil & environmental/water resources engineering [Concrete Mix Design for Normal Strength & Structural Lightweight Concrete, Construction Measurements with and without Fractions, Engineering Surveying Calculations, Air Stripping, Saturated Vapor Pressure for Ice and Water, Density of Water, Dynamic and Kinematic Viscosity of Water, Specific Gravity and Volume, Unit Weight, Surface Tension of Water, Weighted C Factor, Weighted Curve Number, Darcy friction factor (f), the Reynolds number, Manning's n, Gauckler-Manning-Strickler equations for open channel flow], quick search, return character vectors in order, mortality rate calculations, proportion solver, sum of all digits in a vector to a single integer, string manipulation, a version of linear interpolation for use with NAs, Python compatible floor division function, GNU Octave/MATLAB compatible trigonometric functions in degrees, GNU Octave/MATLAB compatible section properties, remainder, modulus, number of dimensions, row vector and column vector tests, fractional differences, size, numel, and length functions.
