The code has several issues that need to be addressed: In the at object, the task_tuning should be passed to the train() function instead of using a separate task_test. The resampling_outer or custom resampling scheme is not being used correctly. When creating the at$train() function, you need to pass the task and resampling arguments separately. In the benchmark(), you are trying to use a grid search over multiple values of a single variable (graph_nop, graph_up, and graph_down).
