I want to predict a variable with Naive Bayes. I tried it with another one from the same dataset and it worked perfect but not with the desired. The variable to predict contains values like "OL","DL" etc.
train_control <- trainControl(method="cv") naiveModel <- train(as.factor(position)~groesse+koerpergewicht+bankdruecken+kniebeuge+maximalkraft_bb+maximalkraft_l+maximalkraft_r+schnellkraft_l+schnellkraft_r+sprint_10m+sprint_20m,data, trControl=train_control, method="nb") Something is wrong; all the Accuracy metric values are missing: Accuracy Kappa Min. : NA Min. : NA 1st Qu.: NA 1st Qu.: NA Median : NA Median : NA Mean :NaN Mean :NaN 3rd Qu.: NA 3rd Qu.: NA Max. : NA Max. : NA NA's :2 NA's :2
