[R] Y in Kohonen xyf function

[chalabi.elahe at yahoo.de]

Hi Kimmo,

Thanks for your reply, Here is a part of my df:

 
     'data.frame':  562 obs. of 128 variables
     $ TE         :int 37 37 35 34 37 37 35 33 32 ...
     $ TR         :int 11 11 8 13 11 8 15 12 8 .....
     $ BW         :int 150 191 128 145 200 191 ........
     $speed       :int 4 4 3 3 2 1 4 1 2 3 ..........
and I want to cluster my data based on speed, to see the coming costumer's protocols fall into which speed group and I think I need to bring this speed column in Y element of xyf

Hi!

Some sample data could help us to help you...

But have you read '?xyf' in order to ensure that your 'Y' is what 'xyf' 
expects it to be?

What kind of error messages do you get?

Regards,
Kimmo
