Initialise with a regular map

[milankl]

At the moment the som.codes are initialised with random rows from the input data. In case one wants to have a more regular gridding intially, something like this works

som = initSOM(train,nx,ny)
som.codes[:,:] = som.grid

However, wouldn't it be nice to have an optional argument in initSOM, for regularly spaced codes given min,max of the dataset?

That's indeed a good idea - I will add this as soon as I find some time!
Thank you for the hint.
