getCodes: Extract codebook vectors from a kohonen object

In e-sensing/kohonenDTW: Supervised and Unsupervised Self-Organising Maps for Satellite Image Time Series

Description

Utility function for extracting codebook vectors. These are present as a list element in a kohonenDTW 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 kohonenDTW.
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.
