### Description

plots a SOM map generated by "sits_som_map" The plot function produces different plots based on the input data:

- "codes": Plot the vector weight for in each neuron.

- "mapping": Shows where samples are mapped.

### Usage

    ## S3 method for class 'som_map'
    plot(x, y, ..., type = "codes", band = 1)

### Arguments

`x` | Object of class "som_map"
`y` | Ignored
`...` | Further specifications for plot.

    ## Not run:
    # Produce a cluster map
    samples_mt_2bands <- sits_select(samples_modis_4bands, bands = c("NDVI", "EVI"))
    som_map <- sits_som_map(samples_mt_2bands)
    # Plot the clusters
    plot(som_map, type = "codes")
    # Plot kohonen map showing where the samples were allocated
    plot(som_map, type = "mapping")
