Get the inner folds for the nested resampling
     
    get_inner(FINAL, NU, REPS, SPCV)
    Arguments
    
    
    
      | FINAL | 
      logical, selects the type of runs, if FALSE trains, else predict
  | 
    
    
      | NU | 
      numeric, number of folds for the \(\nu\)-fold cross-validation
  | 
    
    
      | REPS | 
      numeric, number of repetitions for the repeated \(\nu\)-fold cross-validation
  | 
    
    
      | SPCV | 
      logical, if TRUE activates the spatial cross-validation. This also deactivates the stratification of the folds.
