Re: [Gretl-users] script: open Stata data file - save string-table

Thanks Sven. I took a look at it, but it doesn't help. My case: I followed an R-Script, where (because it is R) you can directly work with strings as factors. Now, I want to load the data in Gretl and perform some similar analysis there. Gretl converts the strings to numerics. In some cases, it keeps them (individual codes) but not if they are factors. For example, country names are changed to numerical factors. I cannot find this information in the new Gretl data-set. From the log, this corresponds to: A minimum working example: You may try with the following Data Set from Gesis: (ZA3778: EVS - European Values Study 1999 - Germany) https://dbk.gesis.org/dbksearch/download.asp?db=E&id=50392 In this case, after opening it with Gretl, the version number is transformed and the string is stored (double klick the variable to see it). But for all the (factorial) items from the questionary, only the new code is saved, the mapping is only visible in the string_table.

I find that chapter 15 of the guide explains how to see the numeric codes for the strings (print city --byobs --numeric) and that you can access them apparently as a vector with curly braces ({city}). From that you can re-build your string table if needed. Also I see in that chapter that if you copy the string series you get the numeric codes (only) in the new series (series citycodes = city). And finally there's the strvals() function which retrieves all the string values in a series and puts them in a strings array. Note that ten minutes ago I didn't know any of these things. I just searched for "string table" in the user guide. I'm glad you asked the question so I could learn a new aspect of gretl, so I'm not saying you shouldn't have asked. I think such questions are perfectly OK. I just want to point out (or repeat) that the documentation we have is really in good shape. cheers, sven _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
