#' Tropheus dataset
#'
#' A data frame of 723 observations of 57 variables extracted from a freely available dataset,
#' downloaded from the Dryad digital repository (\url{https://doi.org/10.5061/dryad.fc02f}).
#' The observations correspond to cichlid fishes of the species \emph{Tropheus moorii}
#' (color morphs 'Kaiser' and 'Kirschfleck') and \emph{T. polli} collected from eight locations
#' of Lake Tanganyika (Kerschbaumer et al., 2014).
#' The main numerical variables provided are the 2D Cartesian coordinates of 19 landmarks
#' quantifying the external body morphology of adult fishes
#' and the genotypes for 6 microsatellite markers.
