Changes in version 0.91                         

  - Importing data. When importing network data as a similarity matrix,
    network data (edgelist or matrix) first gets transformed into a
    undirected adjacency matrix. Then the adjacency matrix gets
    transformed into a similarity matrix.

                 Changes in version 0.9.2 (2016-06-08)                  

  - Fixing vignettes. Put external plots in vignettes folder. Use
    png::readPNG and grid::grid.raster to render plots in vignettes.
