In Momocs: Morphometrics using R

Calibrate using reconstructed shapes

Description

Calculate and displays reconstructed shapes using a range of harmonic number. Compare them visually with the maximal fit. This explicitely demonstrates how robust efourier is compared to tfourier and rfourier.

Usage

calibrate_reconstructions_efourier(x, id, range = 1:9)

calibrate_reconstructions_rfourier(x, id, range = 1:9)

calibrate_reconstructions_tfourier(x, id, range = 1:9)

calibrate_reconstructions_sfourier(x, id, range = 1:9)

calibrate_reconstructions_npoly(
  x,
  id,
  range = 2:10,
  baseline1 = c(-1, 0),
  baseline2 = c(1, 0)
)

calibrate_reconstructions_opoly(
  x,
  id,
  range = 2:10,
  baseline1 = c(-1, 0),
  baseline2 = c(1, 0)
)

calibrate_reconstructions_dfourier(
  x,
  id,
  range = 2:10,
  baseline1 = c(-1, 0),
  baseline2 = c(1, 0)
)

Arguments

x	the Coo object on which to calibrate_reconstructions
id	the shape on which to perform calibrate_reconstructions
range	vector of harmonics on which to perform calibrate_reconstructions
baseline1	(x; y) coordinates for the first point of the baseline
baseline2	(x; y) coordinates for the second point of the baseline

Value

a ggplot object and the full list of intermediate results. See examples.

#' you may prefer efourier...
shapes %>%
    calibrate_reconstructions_rfourier(id=1, range=1:6)

#' you may prefer efourier... # todo
