chromato_env16          Display the multidimensional ecological niche
                        of a species with a species chromatogram.
combina_niche3          Estimate the degree of niche overlapping among
                        species from their chromatograms.
data_abundance          Abundance of 14 pseudo-species. A dataset
                        containing the abundance values of 14
                        pseudo-species in 100 samples. The
                        environmental conditions associated with each
                        samples are described in the environment
                        dataset. Pseudo-species v1 and v2, v3 and v4,
                        v5 and v6, v7 and v8, v9 and v10, v11 and v12,
                        v13 and v14 have the same niche.
environment             Three fictive environmental variables A dataset
                        containing the values of three fictive
                        envionemental variables in 100 samples. The
                        corresponding pseudo-species abundance in each
                        sample are available in the data_abundance
                        dataset.
moymob1                 m order simple moving average.
nanmean4                Mean of the n highest values of a vector.
niche_difer2            Nested function for niche overlapping
                        estimation with 'combina_niche3.R' and
                        'niche_differ_sp.R'.
niche_difer_sp          Nested function for niche overlapping
                        estimation with 'combina_niche3.R'.
opti_eury_niche2        Optimums and amplitudes estimations along each
                        niche dimension.
