somspa
creates a Self-Organizing Map from spatial data.
somspa(x, ...)
x |
A |

Other arguments passed to methods from |
x
should be created by sominp
.
The output somsp
objects can be plotted by plot
and plot_ts
functions or summarized by summary
A somsp
object, which contains:
A summary data.table
with the coordinates of each SOM node, the distances of objects
to their corresponding winning unit, the number of points of each node, as well as the median
latitude and longitude of each node coordinates and their standard deviation.
A Self-Organizing Map object (see also kohonen
).
The sominp
object used as input for the SOM, with an id number coressponding to
location and a node number to the classification group of SOM.
