Hello, I got the following message and therefore report this problem: 2007-07-06 18:02:54.862 R[248] *** REngine.runREPL: caught ObjC exception in the main loop! *** Please report the following error on r-sig-mac@r-project.org along with the full description of how to reproduce it: *** reason: *** -[NSURL initFileURLWithPath:]: nil string parameter *** name: NSInvalidArgumentException, info: (null) *** Version: R 2.5.1 (42083) R.app R 2.5.1 GUI 1.20 (4535)/i386 Consider saving your work soon in case this problem leads to a full crash. It appears when opening a file which is located in a folder with an umlaut (ä,Ö,ü). It doesn't bother me, as I figured the reason out and jsut renamed the folder, but could perhaps be problematic for beginners who have no idea what's going on?! B.t.w. it worked with earlier versions of R (at least since 2.4). Best regards, Ralf ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Ralf B.
