#' pcev: A package for computing principal components of explained variance.
#'
#' PCEV is a statistical tool for the analysis of a multivariate response vector.
#' It is a dimension-reduction technique, similar to Principal Components
#' Analysis (PCA), which seeks the maximize the proportion of variance (in the
#' response vector) being explained by a set of covariates.

#' Methylation values around BLK gene
#'
#' A dataset containing methylation values for cell-separated samples. The methylation was measured
#' using bisulfite sequencing. The data also contains the genomic position of these CpG sites, as
#' well as a binary phenotype (i.e. whether the sample comes from a B cell).
#'
#' Methylation was first measured at 24,068 sites, on 40 samples. Filtering was performed to keep
#' the 25\% most variable sites. See the vignette for more detail.
#'
#' A second sample of the methylation dataset was extracted. This second dataset contains
#' methylation values at 1000 CpG dinucleotides.
#'
#' @format The data comes in four objects:
#' \describe{
#' \item{methylation}{Matrix of methylation
#' values at 5,986 sites measured on 40 samples}
#' \item{pheno}{Vector of phenotype, indicating
#' whether the sample comes from a B cell}
#' \item{position}{Data frame recording the position of
#' each CpG site along the chromosome}
#' \item{index}{Index vector used in the computation of
#' PCEV-block}
#' \item{methylation2}{Matrix of methylation values at 1000 sites measured on 40
#' samples}
#' \item{pheno2}{Vector of phenotype, indicating the cell type of the sample (B cell, T cell, or Monocyte)}
#' \item{position2}{Data frame recording the position of each CpG site along the chromosome} }
