Ranger could not work with caret
Hello, Please post data in dput format, without it it's difficult to tell. If I substitute mpg for act_effort mtcars for tr keeping everything else, I don't get any errors. And the error message says clearly that the error is in tr (data). Can you post the output of dput(head(tr, 30))? Rui Barradas ?s 19:32 de 30/06/2022, Neha gupta escreveu:
I posted it for the second time as I didn't get any response from group
members. I am not sure if some problem is with the question.
I cannot run the "ranger" model with caret. I am only using the farff and
caret libraries and the following code:
boot <- trainControl(method = "cv", number=10)
c1 <-train(act_effort ~ ., data = tr,
method = "ranger",
tuneLength = 5,
metric = "MAE",
preProc = c("center", "scale", "nzv"),
trControl = boot)
The error I get is the repeating of the following message until I interrupt
it.
Error: mtry can not be larger than number of variables in data. Ranger will
EXIT now.
