<code>integer</code>. The number of harmonics to use

nb.h

<code>integer</code>. The number of smoothing iterations to perform.

smooth.it

<code>logical</code>. Whether to print or not diagnosis messages.

norm

<code>logical</code>. Whether to define the first point of the outlines as an homologous point, and thus preserve this information. See Details and References in <a href="/link/efourier?package=Momocs&version=0.2-6" rd-options="" data-mini-rdoc="Momocs::efourier">efourier</a>.

<code>eFourier</code> performs an elliptical Fourier analysis on a <code>Coo</code>-class object, with the specified parameters (number of harmonics and number of smoothing iterations) and returns a <code>Coe</code>-class object containing harmonic coefficients (usually normalized). It accepts the same arguments as the function <a href="/link/efourier?package=Momocs&version=0.2-6" rd-options="" data-mini-rdoc="Momocs::efourier">efourier</a>.

Momocs is intended to ease and popularize shape analysis
        of outlines (especially using elliptical Fourier analysis). It
        mostly hinges on the functions developed in Morphometrics with
        R (Claude, 2008). From outline extraction of images and
        elliptical Fourier calculation to multivariate analysis and the
        visualization of transformations within the morphological
        space, Momocs provides a complete and convenient toolkit to
        specialists within every field that are, or may be, interested
        in morphological comparisons of outlines.

eFourier: Calculates elliptical Fourier analysis on `Coo` objects.
