I'm trying to apply the caret package to my conditional inference tree model, as I need to tune the parameters for said model. I can see what the other options for the train function refer to, but I was wondering, what is tuneLength ?
I have tried to apply the k-fold cross validation tuning method to achieve the best parameters for my model, but I can't understand what the option tuneLength in the train function for the caret package refers to. Is it some parameter which should be fixed, or how is it calculated?
Thank you in advance.
