increment.fv {spatstat.explore}R Documentation

Increments of a Function

Description

Compute the change in the value of a function f when the function argument increases by delta.

Usage

increment.fv(f, delta)

Arguments

f

Object of class "fv" representing a function.

delta

Numeric. The increase in the value of the function argument.

Details

This command computes the new function

g(x)=f(x+h)f(xh)g(x) = f(x+h) - f(x-h)

where h = delta/2. The value of g(x)g(x) is the change in the value of ff over an interval of length delta centred at xx.

Value

Another object of class "fv" compatible with X.
