#124 FIXED IN SVN: Changing variable to factor can destroy data

Donatas G.

Editing factor levels for numeric data and then changing data type to factor destroys the data. I have reported the bug a while ago. It happens again at least as of RKWard 5.7, it can be reproduced exactly the same way as described in the previous bug report.

    Many thanks for reporting. Actually, I think this differs a bit from the previous bug report. Then, the problem was changing to factor, when levels had already been set. Now it's changing to factor, when no (or not enough) levels have been set. Probably this has been an issue, before, but may have been papered over by some other issues that have been fixed, meanwhile.

    I have fixed this in SVN (I hope, I finally got it right).

    I would be very much appreciated, if you could do some testing: http://p.sf.net/rkward/svn for instructions. For Ubuntu, a fixed version should be available from our daily build archive, tomorrow (https://launchpad.net/~rkward-devel/+archive/rkward-dailys).

    Hi, thank you for fixing the bug. It does appear to be fixed, i did all kinds of manipulations with data and it did not disappear at any point this time.
