In monogeneaGM: Geometric Morphometric Analysis of Monogenean Anchors

#' Raw landmark coordinate data for 13 \emph{Ligophorus} species
#'
#' This data set contains raw landmark coordinate data for samples from 13 \emph{Ligophorus} species
#' obtained using the TPSDIG2 program (Rohlf, 2013).
#' @docType data
#' @usage data(ligophorus_tpsdata)
#' @format a list of 13 objects; each object is a list containing objects that are matrices with 44 rows
#' (landmarks 1 to 11 of ventral right,ventral left,dorsal right and dorsal left anchors) and 2 columns (xy-coordinates) 
#' @details Quality control via \code{Qscore} has not yet been applied to this data set (n=530), 
#' so examples of good and poor quality specimens can be inspected using \code{polyVis}.
