Calculate fluctuating asymmetry

Source: R/calc_fageo.R

[Experimental]

Function uses bilat.symmetry to calculate fluctuating asymmetry (FA) component for each template. FA score is calculated as distance between FA component and mean symmetric shape

calc_fageo(data, mirroredlandmarks)

Arguments

data

facefuns object or three-dimensional array of dimensions p, k, and n
mirroredlandmarks

Vector specifying index of mirrored landmarks

Value

Returns tibble containing ID and FA values

Examples

data(LondonSet_aligned)
data(mirroredlandmarks)
calc_fageo(LondonSet_aligned, mirroredlandmarks)
