integral.fv: Compute Integral of Function Object

Description

Compute the integral of a function over a specified range.

Usage

# S3 method for fv
integral(f, domain = NULL, ...)

Value

A single numerical value, or a numeric vector.

Arguments

f

A function value table (object of class "fv").

domain

Optional. Range of values of the argument \(x\) over which the density \(f(x)\) should be integrated. A numeric vector of length 2 giving the minimum and maximum values of \(x\). Infinite limits are permitted.

...

Ignored.

Details

This is a method for the generic function integral. It computes the numerical integral $$ I = \int f(x) dx $$ of the function object f. If domain is specified, the integral is restricted to the interval of \(x\) values given by the domain.

The result is a numeric value or numeric vector containing one entry for each column of function values in f.

Integrals are calculated numerically using the trapezoidal rule restricted to the domain given.
