interval.dist.tobj: Symbolic Objects Distance

Description

Compute a distance between two symbolic objects.

Usage

interval.dist.tobj(sym.obj.x, sym.obj.y, distance = c('hausdorff',
'centers', 'interscal'), p = 2)

Arguments

sym.obj.x

First Symbolic Object

sym.obj.y

Second Symbolic Object

distance

Dsitance to be use

p

The p in the Hausdorff distance

$$d(w_{u_1},w_{u_2}) = \left( \sum_{j=1}^m \Phi_j(w_{u_1},w_{u_2})^p \right)^{1/p}$$

Value

Return a real number that is the distance between sym.obj.x and sym.obj.y
