R: Extract codebook vectors from a kohonen object

getCodes {kohonen} | R Documentation

## Extract codebook vectors from a kohonen object

### Description

Utility function for extracting codebook vectors. These are present as a list element in a `kohonen` object, and themselves are a list as well, with one entry for each data layer. This function returns either a list of codebook matrices (if more layers are selected), or just one matrix (if one layer is selected).

### Usage

    getCodes(x, idx = 1:length(codes))

### Arguments

`x` | An object of class `kohonen`.
`idx` | Indices of the layer(s) for which codebook vectors are returned.

### Value

If `idx` is a single number, a matrix of codebook vectors; if it is a vector of numbers, a list of codebook matrices.
