USCCANA/netdiffuseR: CRAN Release 1.18.0

  • 1. University of Southern California

Description

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.
