BVcliques: Find the bivariate cliques from the marginal data.

Description

The maximal cliques of the intersection graph are obtained by first finding the cliques for the marginal data and then combining them using the algorithm in Gentleman and Vandal (1999).

Usage

BVcliques(intvlx, intvly, Lxopen=TRUE, Rxopen=FALSE, Lyopen=TRUE, Ryopen=FALSE )

Arguments

intvlx

The cliques for one marginal component, alternatively the marginal intervals can be supplied.

intvly

The cliques for the other marginal component, alternatively the marginal intervals can be supplied.

Lxopen

Boolean indicating whether the left end point in the x coordinate is open.

Rxopen

Boolean indicating whether the right end point in the x coordinate is open.

Lyopen

Boolean indicating whether the left end point in the y coordinate is open.

Ryopen

Boolean indicating whether the right end point in the y coordinate is open.

Value

A list of the maximal cliques of the intersection graph of the data.
