an object of class RedPort, which builds the interface between R and RedeR
Java server.
pan
an object of class PAN, which includes the inferred posterior association
network and functional modules.
mod.pval.cutoff
a numeric value specifying the p-value cutoff for selecting significant functional
modules.
mod.size.cutoff
an integer value specifying the minimal size of functional modules.
avg.degree.cutoff
a numeric value specifying the cutoff of module density, which is the ratio of
predicted significant associations to all possible associations.
filter.effects
a logical value specifying whether or not to filter out modules that are not of
interest. In this application to Ewing's sarcoma, modules associated with
positive loss-of-function can be filtered out because we are only interested in
modules related to inhibiting growth and proliferation of cancer cells.
Details
The inferred functional modules are represented in a very compact layout in
RedeR, as many of them are nested to each other due to the nature of
hierarchical clustering. Four arguments can be specified to filter modules.
More details about module filtering procedures can be found in the Methods
section of Wang X et al., 2012.
