Hi again! According to '?xyf', the function is expecting following parameters: (1) data = a matrix, with each row representing an object. So, please ensure that your data is a matrix (2) Y = property that is to be modelled. In case of classification, Y is a matrix of zeros, with exactly one

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

Re: [R] Y in Kohonen xyf function

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 16.06.2016, 15:13, ch.elahe via R-help wrote: Is there any answer? Hi all, I have a df and I

[R] Y in Kohonen xyf function

Is there any answer? Hi all, I have a df and I want to use supervised Self Organizing Map to do classification. I should use Kohonen library and xyf function from it. As you know the xyf function looks like this and I have problem defining my Y:
