CRAN Release 1.18.0

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.
