compute a maximum scoring subnetwork from p-values of the nodes of a network.
The function wraps around the main steps of BioNet including fitBumModel
, scoreNodes
, runFastHeinz
to compute a subnetwork.
1 | callBionet(edgelist, nodelist, pval, fdr)
|
edgelist |
a data frame of edges contains at least a source column (1st column) and a target column (2nd column). |
nodelist |
a data frame of nodes contains node attributes e.g. node id, node name, node xref. Default is NULL. |
pval |
a numeric vector of p-values with name attributes identical to the names of network nodes. |
fdr |
a numeric value specifying false discovery rate. Default is 0.05. |
list of data frame of nodes and data frame of edges with the following components:
nodes:
nodeAttributes
= node attributes provided
score
= node score: positive values = signal content and negative values = background noise
edges:
source, target
edgeAttributes
= edge attributes provided
Return list of empty data frame if error or found nothing.
