R segfaults \* as the data is personal data of other people I would rather not put it some place with public access. This happens with a gentoo \(rkward-0.4.7\) build as well as with a fresh manual build of rkward-0.4.7a. If you could use further information, do not hesitate to tell me so.
Logged In: YES user\_id=300591 Originator: NO In the development version of RKWard, I found and fixed some bugs in the data editor, recently. If possible, could you try, whether you can reproduce the crash, there \(http://rkward.sourceforge.net/wiki/index.php?title=RKWard\_SVN\)? Could you perhaps anonymize the data in some way or another and/or strip it down to just a few cases \(in a way that it still triggers the crash\), and make it available, then? This would help a lot in trying to figure out, what exactly is going wrong.

-- Originally posted by (AT sourceforge.net): smorg -- Logged In: YES user\_id=442636 Originator: YES The crash occured in the latest svn version \(rev 1921\) as well. I will attach a somewhat stripped \(and renamed\) version of my data. File Added: crashy-workspace.r
Logged In: YES user\_id=300591 Originator: NO Sorry for the long delay. I've finally investigated this bug. It was caused by mishandling of logicals, which are contained in your data.frame. This should now be fixed in SVN. If you're still around, it would be nice, if you could give it a try to confirm the bug is fixed \(http://rkward.sourceforge.net/wiki/index.php?title=RKWard\_SVN\). \(Note: Logicals are still not handled correctly in the data editor, but should be useable, now\)
