regularized dfa rda (Klar): problems with predictions
...predict the groups from the test/validation sample. The exmaples of the R documantation and some online webpage also do not work. Does anybody know what I have done wrong?
Here my code
# I want to use the first 6 observations for validationg the model, case 7 to 36 are
# used for the trianing:
n_fold<-sample(1:36,36)
testset<- n_fold[1:6]
trainset<- n_fold[-(1:6)]
# regularized DFA with default setting (works fine)
z <- rda(group ~ ., data=test[trainset,])
#Now the prediction:
a<-predict(z,data=test[testset,])$class
Error in predict.rda(z, data = test[testset, ]) :
