Indices of a bipartite network at the link level
Computes various indices of a network at the link-level, i.e. for each cell of the network matrix
linklevel(web, index=c("dependence", "endpoint"))web |
A matrix with pollinators as columns and plants as rows. Alternatively, when used on e.g. species occurrences across islands, rows are islands. |

Vector of indices to be computed at the link level; options are:
|
For summaries of such indices see networklevel. It's still early days for this function ...
Returns a list of indices, each entry being a matrix of the same dimensions as the input web.
This function aims to facilitate analyses at the link level. So far, most studies at this level did not correct for the fact that observations per cell are clearly non-independent, nor for the abundances of the species, which also greatly affect indices. Room for improvement, but little room for new findings ...
