comDCGL: Sort out common DCGs and DCLs in multi-diseases

Description Usage Arguments Value Author(s) Examples

Description

common DCGs and DCLs maybe imply the similar regulation mechanisms which are the underlying reasons to disease relationships. Therefore comDCGL are implemented to sort out shared DCGs and DCLs in multi-disease.

Usage

1
comDCGL(Ndis = 3, DCEA.disn, DisNames = c("AA", "CKD", "T2D"), cutoff = 0.05, tf2target)

Arguments

Ndis

Disease number.

DCEA.disn

DCEA results for multi-diseases.

DisNames

Disease names.

cutoff

the cutoff of 'q.vaule' in DCEA results; must be within [0,1]; If there is no 'q.value' value (when N=0 in DCEA function), 'dC' will be sorted in decreasing order and retained the highest by 'cutoff' percent.

tf2target

a data frame or matrix for TF-to-target interaction pairs.

Value

A list with two components:

comDCGs

Displaying common DCGs with annotated regulator information.

comDCLs

Displaying common DCLs with annotated regulation relationship information.
