Changes in netdiffuseR version 1.18.0 (2017-07-16) New functions bootnet implements network bootstrapping based on Snijders and Borgatti (1999) mentor_matching implements Valente and Davis (1999) Mentor matching algorithm. including a plot method. approx_geodesic an alternative to igraph::distances and sna::geodist. computes geodesics up to a certain number of steps and returns a sparse matrix. matrix_compare Efficiently compares two sparse matrices looking only at the valued cells. as_dgCMatrix Coerce matrix-like objects into dgCMatrix objects (sparse matrices from the Matrix package). fitbass Fits the Bass Diffusion Model to an observed vector of cumulative adopters. The estimation is done via stats::nls. netmatch and netmatch_prepare (on development) implement matching estimators with network data. Bugs Fixes dgr returned with error when self == TRUE In some calls to igraph::graph_from_adj... sorting of vertices was not preserved. The matrix method in egonet_attrs was passing a list of vertices instead of the attributes. Fixed. transformGraphBy was returning with error when the time periods ranged other than 1, 2, ... New Features rgraph_er is now significantly faster (orders of magnitude compare to previous versions). rgraph_ba is faster too. moran now returns the sd, expected and p-value. exposure now receives static graphs in alt.graph with a warning. rewire_graph now also uses QAP. This affects directly to structu_test.
