SimulNetworkAdjMatrix: 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

Value

Examples

library(G1DBN)
## number of genes
p <- 10
## the network - adjacency Matrix
MyNet <- SimulNetworkAdjMatrix(p,0.05,c(-1,0,0,1))
MyNet

## initializing the B vector
B <- runif(p,0,0.5)
## initializing the variance of the noise
sigmaEps <- runif(p,0.1,0.8)
## initializing the process Xt
X0 <- B + rnorm(p,0,sigmaEps*10)
## number of time points
n <- 20

## the AR(1) times series process
Xn <- SimulGeneExpressionAR1(MyNet$AdjMatrix,B,X0,sigmaEps,n)
