The stochastic (also called on-line) version of the Self-Organising
Map (SOM) algorithm is provided. Different versions of the
algorithm are implemented, for numeric and relational data and for
contingency tables as described, respectively, in Kohonen (2001)

<doi:10.1016/j.neucom.2013.11.047> and Cottrell et al (2004)
<doi:10.1016/j.neunet.2004.07.010>. The package also contains many
plotting features (to help the user interpret the results), can
handle (and impute) missing values and is delivered with a
graphical user interface based on 'shiny'.
