#' Enamel thickness and other molar data for hominoids.
#' 
#' A dataset containing enamel thickness, enamel area, and other data (see
#' below) for 195 specimens representing 13 species of hominoids.

#' @usage \code{data(enamelthickness)}
#' @format A data frame with 195 rows and 9 variables:

#'   The data were extracted from the supplementary material. The following
#'   modifications were made:
#'   \itemize{
#'     \item citation and basis for tooth identification columns dropped \item
#'     consolidated LM1 and RM1 into just M1, and the same for M2 and M3; none
#'     of the analyses in the paper itself differentiate between right and left 
#'     \item fixed an apparent error in the values for bcd, aet, and ret for the
#'     specimens of unknown taxonomic attribution (column values were rotated)
