The rule is that a function only has access to the data range that was passed in by the caller. You can subsample within a function but smpl --full just takes you back to the dataset state as the caller specified it. If you want a function to do something with a sub-sample and also to do something with the full dataset, you can pass in the full dataset (that is, do "smpl --full" before calling the function) but pass in the sub-sample information as argument(s). For example int arguments t1 and t2, or a dummy series.
