Problems with caret sbf objects

[nebfield]

Minimal dataset

library(caret)
library(iml)
dat <- twoClassSim(100)
X <- dat[,1:5]
X$y <- dat[["Class"]]

Minimal, runnable code

tr <- sbf(
  y ~ .,
  data = X,
  sbfControl = sbfControl(
    functions = caretSBF,
    verbose = FALSE,
    method = "cv",
    number = 10
  ),
  trControl = trainControl(classProbs = TRUE),
  method = "svmLinear"
)

Problems start

Predictor$new(tr, X, y = "y")

Prediction task:unknown

pred <- Predictor$new(tr, X, y = "y")
Shapley$new(pred, X, X[1, ])

Error in colMeans(self$predictor$predict(private$sampler$get.x()):
x must be numeric

These problems don't happen if I create Predictor with a fit object extracted from dbf (Predictor$new(tr$fit, ...) but this is a bad idea.

Thanks for making iml. Your book is amazing 😁
