identifyPWTFTGs: Identify TFs in pathways and their target genes - downstream...

Description Usage Arguments Value Examples

View source: R/pwOmics_downstream_analysis.R

Description

This function identifies the transcription factors being part of the pathways of downstream analysis. Subsequently it finds the target genes of these transcription factors from the selected TF-target gene database.

Usage

1
identifyPWTFTGs(data_omics, updown = FALSE)

Arguments

data_omics

OmicsData object.

updown

boolean value; TRUE in case up- and downregulation should be checked individually for intersection; FALSE = default, if only deregulation should be checked for.

Value

OmicsData object: list of 4 elements (OmicsD, PathwayD, TFtargetsD, Status); OmicsD containing omics data set + results (after analysis); PathwayD containing selected pathway databases + biopax model; TFtargetsD containing selected TF target gene databases + TF target gene data.
