matrixNodes: Select nodes and edges from gene regulatory network
In xzheng-ac/scPADGRN: A PADMM approach for reconstructing DGRN using scRNA-seq

Description Usage Arguments Value Examples

This function selects nodes and edges from gene regulatory network

1	matrixNodes(M, edgeRank, nodeRank)

`M`	M is a numerical matrix.
`edgeRank`	edgeRank is the number of non-zero of matrix M.
`nodeRank`	nodeRank is number of nodes that are needed.

M is a matrix whose number of nodes equals to nodeRank.

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (M, edgeRank, nodeRank)
{
    M <- edges(M, edgeRank)
    matrixNode <- nodes(M, nodeRank)
    return(matrixNode)
  }
