## Build a self-organizing map

### Description

Build a self-organizing map

### Usage

    SOM(data, xdim = 10, ydim = 10, rlen = 10, mst = 1,
      alpha = c(0.05, 0.01), radius = stats::quantile(nhbrdist, 0.67) *
      c(1, 0), init = FALSE, initf = Initialize_KWSP, distf = 2,
      silent = FALSE, codes = NULL, importance = NULL)

### Arguments

`data` | Matrix containing the training data
`xdim` | Width of the grid
`ydim` | Hight of the grid
`rlen` | Number of times to loop over the training data for each MST
`mst` | Number of times to build an MST
`alpha` | Start and end learning rate
`radius` | Start and end radius
`init` | Initialize cluster centers in a non-random way
`initf` | Use the given initialization function if init==T (default: Initialize_KWSP)
`distf` | Distance function (1=manhattan, 2=euclidean, 3=chebyshev, 4=cosine)
`silent` | If FALSE, print status updates
`codes` | Cluster centers to start with
`importance` | array with numeric values. Parameters will be scaled according to importance

### Value

A list containing all parameter settings and results
