[Gretl-devel] extension of the dummify function for anonymous series

Hello, I was reminded again of the fact that a construct like dummify($unit) cannot be used, since dummify creates a list and needs information about the name of the input series to name the list members. So the idea is to give dummify another optional (string) argument that provides this naming information. Example of desired usage: list groupdums = dummify($unit, NA, "du") This particular line with the name "du" would be equivalent to "genr unitdum", apart from the fact that the relevant list is directly created in one go. To be clear, dummify($unit) would continue _not_ to work since naming information is missing. And dummify(x, , "better_use_z") would override the "x" name of the input series for the dummy creation. In principle it might perhaps also be interesting to substitute the two optional arguments with a single option bundle, but I don't know if such overloading would be desirable here. thanks sven
