pwed_pd: Physical distance between landmarks in ventral and dorsal anchors of 13 Ligophorus species
Description
This data set contains all pairwise physical distance between landmarks in
ventral and dorsal anchors of samples from 13 Ligophorus species.
Usage
data(pwed_pd)
Arguments
Format
a matrix containing 437 rows (samples) and 110 columns (physical distance)

Khang TF, Soo OYM, Tan WB, Lim LHS. (2016). Monogenean anchor morphometry: systematic value, phylogenetic signal, and evolution. PeerJ 4:e1668.
Details
The pairwise physical distances are estimated from a subset (n=96) of the 437 samples based on a regression equation,
using physical distances between landmarks 1 to 3 and landmarks 1 to 5 and corresponding distances computed from pwdist,
which have arbitrary units.
