2 years ago Hi there,
Ik looks like there is some missing data. Does the training set include all data and columns and aren’t there any missing values in the rating column?

and the error message is:
Error in apply(testOutput[, lev], 1, function(x) x/sum(x)) : dim(X) must have a positive length Calls: train -> train.default -> evalSummaryFunction -> t -> apply Execution halted
Is there any suggestion?

Dear Authors:
I use R version 4.1.2 and run commands line by line in the script of Qoala_T_B_subset_based_github.R. An error occurs during training step:
rf.tune = train(y=training$Rating, x=subset(training, select=-c(Rating)), method = "rf", metric = "ROC", trControl = ctrl, ntree = 501, tuneGrid=expand.grid(mtry = c(8)), verbose=FALSE)
and the error message is:
Error in apply(testOutput[, lev], 1, function(x) x/sum(x)) : dim(X) must have a positive length Calls: train -> train.default -> evalSummaryFunction -> t -> apply Execution halted
Is there any suggestion?
