ff_math: Math for ff vectors

In ffbase: Basic Statistical Functions for Package 'ff'

Description

These mathematical functions implement ff_vector specific math and handle the following functions from the Math family:

• Math: "abs", "sign", "sqrt", "ceiling", "floor", "trunc", "log", "log10", "log2", "log1p", "acos", "acosh", "asin", "asinh", "atan", "atanh", "exp", "expm1", "cos", "cosh", "sin", "sinh", "tan", "tanh", "gamma", "lgamma", "digamma", "trigamma"

• Math2: "round", "signif"

The operators require x to be an ff_vector.
