dataWurdinger {GRridge} | R Documentation

## R-objects related to the mRNAseq data

### 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.

### Usage

    data(dataWurdinger)

### Details

This data is used for illustration in the application paper below.

### Value

### Examples

    data(dataWurdinger)

    # Transform the data set to the square root scale
    dataSqrtWurdinger <- sqrt(datWurdinger_BC)
    #
    #Standardize the transformed data
    datStdWurdinger <- t(apply(dataSqrtWurdinger,1,
                               function(x){(x-mean(x))/sd(x)}))
    #
    # A list of gene names in the primary RNAseq data
    genesWurdinger <- as.character(annotationWurdinger$geneSymbol)
