In TransBioInfoLab/MethReg: Assessing the regulatory potential of DNA methylation regions or sites on gene transcription

#' @title MethReg: functional annotation of DMRs identified in epigenome-wide
#' association studies
#' @description To provide functional annotations for
#' differentially methylated regions (DMRs)
#' and differentially methylated CpG sites (DMS), \code{MethReg} performs
#' integrative analyses using matched DNA methylation and gene expression
#' along with Transcription Factor Binding Sites (TFBS) data.
#' MethReg evaluates, prioritizes and annotates DNA methylation regions
#' (or sites) with high regulatory potential that works synergistically with
#' TFs to regulate target gene expressions, without any
#' additional ChIP-seq data.
