getCodes: 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))
Value
If idx is a single number, a matrix of codebook vectors;
if it is a vector of numbers, a list of codebook matrices.
Arguments
x
An object of class kohonen.
idx
Indices of the layer(s) for which codebook vectors are
returned.
