## Construction of Gene Co-expression Network

### Description

The function computes the adjacency matrix using the soft threshold parameter to construct a Gene Co-expression Network

### Usage

Adjacency(x, beta, threshold)

### Arguments

 x x is a data frame of gene expression values where rows represent genes and columns represent samples/time points under a particular condition/stress/trait. beta beta is a soft threshold parameter determined from the scale free property of biological networks (Gene Co-expression Network). threshold threshold is a scalar representing the threshold value for the adjacency matrix to construct the Gene Co-expression Network.

### Value

The function returns a list of outputs like adjacency matrix, Node-list and Edge-list for constructing a Gene Co-expression Network at certain threshold level
