## Module Identification for two-layer network

### Description

Algorithm for Module Identification on two-layer network

### Usage

    moduleIdentificationGPFixSSTwolayer(W1, z1, x0, W2, z2, y0, A, lambda1 = 1,
      lambda2 = 1, lambda3 = 1, maxiter = 1000, a1 = 0.5, a2 = 0.5)

### Arguments

`W1` | edge score matrix of the network 1, n_1 x n_1 matrix
`z1` | node score vector of the network 1, n_1-length vector
`x0` | initial solution of network 1, n_1-length vector
`W2` | edge score matrix of the network 2, n_2 x n_2 matrix
`z2` | node score vector of the network 2, n_2-length vector
`y0` | initial solution of network 2, n_2-length vector
`A` | inter-layer links weight, n_1 x n_2 matrix
`lambda1` | parameter in objective, coefficient of node score of network 1
`lambda2` | parameter in objective, coefficient of node score of network 2
`lambda3` | parameter in objective, coefficient of inter-layer links part
`maxiter` | maximal interation of whole procedure
`a1` | parameter in elastic net the same as in `EuclideanProjectionENNORM`
`a2` | parameter in elastic net the same as in `EuclideanProjectionENNORM`

### Value

a list containing solution for network 1 and network 2 and objective

    recall = length(intersect(predictedid,moduleid))/length(moduleid)
    precise = length(intersect(predictedid,moduleid))/length(predictedid)
    F1 = 2*precise*recall/(precise+recall)
    predictedid2<-which(modres[[2]]!=0)
    recall2 = length(intersect(predictedid2,moduleid2))/length(moduleid2)
    precise2 = length(intersect(predictedid2,moduleid2))/length(predictedid2)
    F2 = 2*precise2*recall2/(precise2+recall2)
