#' Gene expression data for human tissues
#'
#' A dataset containing log-fold change of gene expression between 2 human tissues. The fold change were computed based on the expression data generated using Affymetrix array platform (microarray data) and Illumina Hiseq (RNA-seq data). Data from 2 different platform have been normalized and averaged across technical replicates.
