linklevel: Indices of a bipartite network at the link level
Description
Computes various indices of a network at the link-level, i.e. for each cell of the network matrix
Usage
linklevel(web, index=c("dependence", "endpoint"))
Arguments
web
A matrix with pollinators as columns and plants as rows. Alternatively, when used on e.g. species occurrences across islands, rows are islands.
index
Vector of indices to be computed at the link level; options are:
to compute dependence-matrix for each group level;
to compute end-point degrees following Barratt et al. (2004).
<
Value
Returns a list of indices, each entry being a matrix of the same dimensions as the input web.
encoding
UTF-8
Details
For summaries of such indices see networklevel. It's still early days for this function ...
