Description Usage Arguments Value Note Author(s) References Examples

This function calculates Barrat et al. (2004) generalised local clusering coefficient.
See http://toreopsahl.com/2009/01/23/weighted-local-clustering-coefficient/ for a detailed description. By default it defines the triplet value as the average of the two tie weights; however it can also define it differently. See the blog post.
Note: If there are very large tie weights in a network, the geometric method in R fails. However, this can be fixed by transforming the values.
net[,"w"] <- (net[,"w"]/min(net[,"w"]))
This step is not required unless you receive warnings when running the function.

1	clustering_local_w(net, measure = "am")

`net`	A weighted edgelist
`measure`	The measure-switch control the method used to calculate the value of the triplets. am implies the arithmetic mean method (default) gm implies the geometric mean method mi implies the minimum method ma implies the maximum method bi implies the binary measures This can be c("am", "gm", "mi", "ma", "bi") to calculate all.

Returns a data.frame with at least two columns: the first column contains the nodes' ids, and the remaining columns contain the corresponding clustering scores.
