Given a kohonen object with a set of time neurons, plot them.
The plot function produces different plots based on the input data:
"codes": Plot the vector weight for each neuron.
"mapping": Shows where samples are mapped.
.sits_plot_som_map(koh, type = "codes", whatmap = 1)
SOM map produced by "sits_som_map" function
Type of plot ("codes" or "mapping")
What data layer will be plotted.
