random_network: creates random augmented networks X and Y

In SDDE: Shortcuts, Detours and Dead Ends (SDDE) Path Types in Genome Similarity Networks

Description

This function allows the user to create random network X and an associated augmented network Y using either the Erdos-Renyi model or the Barabasi-Albert model.

Usage

random_network(original_node, additional_node, ngroup, edge_ratio,total_edge, type)

Arguments

original_node	the number of nodes in the original network X (default=25)
additional_node	the number of additional node in network Y (default=5)
ngroup	the number of additional taxa groups in network Y (default=1)
edge_ratio	the edge to node ratio (default=between 1 and 5)
total_edge	the number of edges in the fixed model
type	Either 'erdos' for the Erdos-Renyi model, 'barabasi' for the Barabasi-Albert model, 'watts' for the Watts-Strogatz model or 'fixed' fixed model allowing a defined number of edges

Value

Return a data.frame containing g1, g2, the total_nodes and the total_edges numbers of network Y and the total_original_nodes number of network X.

	## Create two networks using the Erdos-Renyi model with 100 nodes in network X 
	## and 10 additional nodes in network Y of 3 types. 
	random_network(100,10,3);
	## Create a random networks of 20 +10 additional node using the  Barabsi-Albert model
	## and compute the corresponding SDDE path types.
	## l <- random_network(20,10,ngroup=1,vertex_ratio=1, type='barabasi');
	## complete_network(l$g1, l$g2);
