SimulNetworkAdjMatrix {G1DBN}
Network object generation
Description
This function builds a object "Network" by simulating a matrix of valued adjacencies from a number of vertices, a proportion of edges and the range of the uniform distribution that is used to build the adjacency matrix. An optional vector of labels may be given.
Usage
SimulNetworkAdjMatrix(Num,EdgesProp,Range,Labels=1:Num)
Arguments
- Num
- number of genes
- EdgesProp
- edges proportion in the network
- Range
- vector with 4 elements specifying range values for the adjacency matrix generation (minimum negative value, maximum negative value, minimum positive value, maximum positive value)
- Labels
- an optional vector of labels for the edges
Values
a list that contains out$Vertices$Num the number of vertices, out$Vertices$Labels a vector of labels of the vertices, out$Vertices$Regulated a vector of the regulated vertices, out$Edges$Prop the proportion of edges, out$Edges$Num the number of edges, out$AdjMatrix an adjacency matrix (binary) and out$A a valued adjacency matrix.
