## 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.
