egonet is a small tool for Social Network Analysis, dealing with egocentric network measures, including Burt's effective size and aggregate constraint and an import code suitable for a large number of adjacency matrices. This is the development version of the egonet R package, available at (there is also an egonet web application: an example of output can be seen at Reference manual is available at This tool allows to read text tables and creates egocentric graphs from them (@wasserman1994social), with the ego actor in the first row and column. The result is a number of square matrices with common input/output connection' names. Thus, given a list of file' names containing the ego-network in the same directory, one can import all the egonets, compute (default) indices on the first subject of each adjacency matrix and then to merge socio-demographic information with the indices. egonet computes Burt's indexes (effective size and aggregate constraint) and other measures from sna package. The ego.gden index calculates the density score in a matrix without "ego" connections. egonet also allow to restrict the analysis to one social circle identified by the name of the alters. This software was cited by D. Halgin and S. Borgatti in the Connections journal as a R package specific to the analysis of ego network data (@halgin2012introduction).
