We pop the value of the old key from the dictionary, and then insert it in again under the new key. Here’s the code, which we’ll stick into the main block in replace():elif isinstance(relation, Path.R_INDEXKEY): source = path.src.theone source[new] = source.pop(source.keys()...
Since this is what you typically need to do, this is one of the biggest stupidities still found in SPSS today. A workaround for this problem is toRECODE the entire low range into some huge value such as 999999999; add the original values to a value label for this value; specify only ...
