R Documentation

Extract landmark data

Description

Read landmark coordinates and scales from a TPS file

Usage

ReadLandmarkData(datafile, m_byscale = T)

Arguments

datafile	TPS file containing two dimensional landmark data
m_byscale	Logical value (Default m_byscale=TRUE). If TRUE, landmark coordinates are multiply by scale

Details

The function returns landmark coordinates (array and data.frame format) and the scale of each specimen. If m_byscale = T the coordinates are multiple by the corresponding scale. ReadLandmarkData only works with TPS files that has only landmark coordinates (presence of CURVES and OUTLINES may cause malfunction).

Value

It returns a 3 element list:

df	Landmark coordinates as a data.frame. Sp factor correspond to species number.
array	Landmark coordinates as a three dimensional array.
