plot_MD_GE_graph: Create molecular descriptors and MoA features interaction...
In angy89/hyQSAR: Hybrid QSAR model

This function takes in input one row of the metrics matrix returned by the tqsar and hqsar functions and plot the interaction graph of genes and MDs

1	plot_MD_GE_graph(model_info, MDMat, GeneMat, neg_th = NULL, pos_th = NULL)

`model_info`	is one row of the metrics matrix
`MDMat`	is the matrix of modelucalr descriptors
`GeneMat`	is the matrix of MOA features
`neg_th`	is a threshold that the user can set up to filter the graph from negative endges. If not null, the plot will contain only the edges with value lower that the neg_th quantile of the distribution of the negative edges weights
`pos_th`	is a threshold that the user can set up to filter the graph from negative endges. If not null, the plot will contain only the edges with value higher that the pos_th quantile of the distribution of the positive edges weights
