Help Pages

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.
