A Simulated Data Set

Description

A simulated data set based on the R code provided by Law et al.'s (2014) paper.

Usage

data("es")

Format

The format is: Formal class 'ExpressionSet' [package "Biobase"]

Details

The simulated data set contains RNA-seq counts of 1000 genes for 6 samples (3 cases and 3 controls). The library sizes of the 6 samples are not equal.

Source

The dataset was generated based on the R code Simulation_Full.R from the website http://bioinf.wehi.edu.au/voom/.
