Description Usage Arguments Value Examples

Calculate topological indices for ecological networks. The mean trophic level and Omnivory and the Level of omnivory are calculated with the function NetIndices::TrophInd()

1	calc_topological_indices(ig, ncores = 0)

`ig`	vector of igraph objects
`ncores`	number of cores used to compute in parallel, if 0 sequential processing is used.

a data.frame with the following fields:

`Size:`	Number of species
`Top:`	Number of top predator species
`Basal:`	Number of basal especies
`Omnivory:`	Proportion of omnivorous species
`Links:`	number of interactions
`LD:`	linkage density
`Connectance:`	directed Connectance
`PathLength:`	average path length
`Clustering:`	clustering coeficient
`Cannib:`	number of cannibalistic species
`TLmean:`	mean trophic level
`TLmax:`	maximum trophic level
`LOmnivory:`

Level of omnivory, quantiﬁes mean of the variety in trophic levels of the preys of a consumer

`Components:`	number of weakly connected components
`Vulnerability:`	mean of number of consumers per prey
`VulSD:`	the standard deviation of normalized Vulnerability
`Generality:`	mean number of prey per consumer
`GenSD:`	the standard deviation of normalized Generality
