Examples

## Loading the geomorph dataset
require(geomorph)
data(plethodon)

## Performing the Procrustes superimposition
proc_super <- gpagen(plethodon$land, print.progress = FALSE)

## Getting the spherical coordinates difference between the two first specimen
difference <- coordinates.difference(proc_super$coords[, , 1], proc_super$coords[, , 2],
                                     type = "spherical", angle = "degree")

## Calculate the area of the coordinates differences
coordinates.area(difference[[1]])
