Dear Alan, Although what you are saying are things that could be improved in PSPP you should remember that PSPP is still under development - it is not version 1.0.
Even in version 1.0 I believe there could be and probably will be things worth improving - recently I had SPSS version 22 installed on my computer in the office - first my colleagues from IT department installed SPSS itself, and then a very large file with bug fixes. Not long ago we had here on PSPP mailing list a large discussion about bugs in various versions of SPSS - I myself know person who found some mistakes in SPSS tables output (it was probably version 12, 13 or 15 then - sorry I don't remember) and after some time received bug fixes correcting this output. And SPSS is commercial product, each version they distribute is considered to be complete and ready to be used. PSPP is developed by people who do that by their goodwill. PSPP is not finished and sometimes we all find things that we want to do but it's not possible because these features are not yet implemented, but I really appreciate the work of PSPP developers and all the people supporting the project. With current PSPP I can do many things the SPSS-way even when I don't have access to SPSS, and some things are easier for me to be done that way rather than in R or recently in Python (although there are other data operations and analysis that are much easier for me to be done in R or Python). Happy New Year to all of you :-) Michał Dubrawski 2014-12-31 0:02 GMT+01:00 <pspp-users-requ...@gnu.org>: > Send Pspp-users mailing list submissions to > pspp-users@gnu.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.gnu.org/mailman/listinfo/pspp-users > or, via email, send a message with subject or body 'help' to > pspp-users-requ...@gnu.org > > You can reach the person managing the list at > pspp-users-ow...@gnu.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Pspp-users digest..." > > > Today's Topics: > > 1.
