Hi all,
I want to use Self Organizing Map in R for my data. I want my training set to
be the following subset of my data:
subdf=subset(df,Country%in%c("US","FR"))
next I should change this subset to a matrix but I get the following error:
data_train_matrix=as.matrix(scale(subdf))
error in colMeans(x,na.rm=TRUE):'x' must be numeric
Can anyone help me to solve that?
Thanks for any help
Elahe
