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:
xyf(data,Y,grid=somgrid(),rlen=100,alpha=c(0.05,0.01))
I want to do classification based on a column which shows the speed that a
protocols is run, and this column is the following:
$speed :num 4 4 3 3 3 1 1 1 2 1 4 4 3
numbers from 1 to 4 show the speed from very fast to very slow protocols. so the
property I want to be modeled is df$speed, but I don't know how should I
bring it in xyf function. Does anyone know how to do that? I also added my train
set ans test set:
dt=sort(sample(nrow(df),nrow(df)*.7))
train=df[dt,]
Xtraining=scale(trian)
Xtest=scale(-trian)
center=attr(Xtrianing,"scaled:center")
scale=attr(Xtraining,"scaled:scale")
xyf(Xtraining,........,grid=somgrid(10,10,"hexagonal"))
Thanks for any Help,
Elahe
Is there any answer?

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?
