Description Usage Arguments Details Value References See Also Examples
This function takes the adjacency matrix, the data sets folder path and number of mutual information steps for the therhold mutual information. It returns averaged mutual information matrix, averaged mutual information matrix for the inferred edges, the averaged mutual information values for the inferred edges, the averaged mutual information values for the non-inferred edges, maximum F-scores, threshold mutual information values that gives maximum F-score, and also the same input adjacency matrix of genes.
1 | evalnetworks(E, net, infilepath)
|
E |
number of experiments. |
net |
Adjacency matrix of genes (not symmetric). |
infilepath |
The path of the directory, where all the data files kept. |
It reads all the mutual information matrices from the folders and take the average and then derive the other parameters from it.
evalnetworks
returns an object of class '"res"' which is a list with components:
aveMImat |
averaged mutual information matrix of the overall experiments. |
rmat |
averaged mutual information matrix for the inferred edges of the overall experiments. |
tpre |
All the averaged mutual information values for the inferred edges. |
fnre |
All the averaged mutual information values for the non-inferred edges. |
Fscores |
Maximum F-score values for all the experiments. |
Ithr |
The threshold mutual information values, which gives maximum F-score, for all the experiments. |
net |
Adjacency matrix of genes (not symmetric). |
