MEGENA (version 1.3.7)

planaritytest: Boyer-Myvold Planarity test of a network

Description

wrapper function of _MEGENA_planaritytest. imports from Boost graph library, and test planarity of a network

Usage

planaritytest(N, rows, cols)

Arguments

N

must be an integer. number of nodes in the network.

rows

first column of edgelist. a vector of integers.

cols

second column of edgelist. a vector of integers.

Value

TRUE/FALSE is returned to indicate planarity. (TRUE -> network is planar).

Details

cbind(rows,cols) is equivalent to the two column edge list of the network. We assume that the network is undirected.

Examples

# NOT RUN {
# test simplest case of planar network (a 3-clique).
planaritytest(as.integer(3),c(1,1,2),c(2,3,3))
# }
