| 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. |
