Reusing code vectors/ prototypes in SOMBrero

[SnehaVidekar]

trainSOM() takes proto0 parameter as input. Can prototype from already trained SOM be passed while training new data?

Trying to reuse the code vector/prototype. I am trying below code :

Brero1.som <- trainSOM(x.data = DATA, nb.save=2,
                      dimension = c(5,5),
                       radius.type="letremy",
                       dist.type="letremy",
                         maxit=maxit_var,
                       eps0=0.0100000,init.proto="random", scaling ="unitvar")

Brero2.som <- trainSOM(x.data = New_DATA, nb.save=2,
                       dimension = c(5,5),
                       radius.type="letremy",
                       dist.type="letremy",
                         maxit=maxit_var,proto0=Brero1.som$prototypes
                       eps0=0.0100000,init.proto="random", scaling ="unitvar")

Error: Error in run.trainSOM(x.data, ...) : initial prototypes dimensions do not match SOM parameters: in the current SOM, prototypes must have rows and columns

I have tried different sizes for the prototypes. Has anyone tried this proto0 ??

Thanks for the bug report. I found the error and posted a bug fix on github (see previous comment). I will try to shortly package this bug fix in a new release and add tests to automatically check this feature. Meanwhile, feel free to use the github version. Thank you for your help.

Thank you. It is working now.
