margarita: Support functions for texmex

#' Data included in the margarita package
#'
#' @name lb
#' @aliases dm
#' @docType data
#' @details The \code{liver} data, as found in the texmex (Southworth and Heffernan)
#'          package, restructured so as to resemble CDISC SDTM datasets. The
#'          lab values (ALT, AST, TBL and ALP) and dose groups are identical to
#'          the \code{liver} dataset. The remaining values (age, sex, race and
#'          so on) are simulated. The data are broken down into the lab data
#'          (\code{lb}) and (largely fictional) `demography' data (\code{dm}).
#'          The purpose is to illustrate the usage of some of the functions provided
#'          by margarita to aid transformation of SDTM data into evm-ready analysis
#'          data.
