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.
