dataWurdinger: R-objects related to the mRNAseq data

Description Usage Details Value Source Examples

Description

The four objects are:

datWurdinger_BC: A matrix containing preprocessed mRNA sequencing data (quasi-gausian scale, normalized). Columns are samples (81 samples with Breast Cancer and Colorectal Cancer) and rows are features (18410 features).

respWurdinger: A factor containing responses for samples with Breast cancer (n=40) and colorectal cancer (n=41)

annotationWurdinger: A list containing ensembleID, geneSymbol, entrezID and chromosome location.;

coDataWurdinger: A list containing co-data sets from external sources, namely (i) a list of genes that are expressed in platelets; (ii) immunologic signature pathway and; (iii) transcription factor based pathway and a list of cancer somatic genes.
