#' Datasets

#' \code{alcohol}, \code{chlamydiae} and \code{age} datasets
#'
#' The \code{alcohol} dataset was taken from a study of the dietary
#' association with the gut microbiome (Wu, 2011). Here we include the
#' alcohol intake as the primary phenotype. The OTU abundance data consists
#' of 98 samples with 949 OTUs with prevalence > 10%. The raw counts are
#' normalized to account for variable library sizes.
#'
#' The \code{chlamydia} dataset is taken from a 16s rRNA diversity study
#' narrowed to the Chlamydiae bacteria taxon, originally appearing in PNAS.
#'
#' The \code{age} dataset comes from Brito et al. (2016)
