exprMatrix {AffiXcan} | R Documentation

## Expression data of two genes for 229 individuals

### Description

Toy dataset used in examples to describe affiXcanTrain() function.

### Usage

    data(exprMatrix)

### Format

An object of class `SummarizedExperiment`.

### Details

The data consist in a SummarizedExperiment object that contains a matrix of expression values (RPKM) of two randomly chosen genes ("ENSG00000139269.2" and "ENSG00000256377.1") for 229 individuals of european descent. The data was retrieved subsetting the RNA-sequencing data of EBV-transformed lymphocytes from the GEUVADIS public dataset (see 'source')
