Description Usage Arguments Value Examples

This function returns to M. M is a matrix whose number of non-zero entries equals to edgeRank.

1	edges(M, edgeRank)

`M`	M is a numerical matrix.
`edgeRank`	edgeRank is the number of non-zero of matrix M.

M is a matrix whose number of non-zero entries equals to edgeRank.

## The function is currently defined as
function (M, edgeRank)
{
    M[rank(abs(M)) < (nrow(M) * ncol(M) - edgeRank + 1)] <- 0
    return(M)
  }
