I'm still somewhat worried about future clashes. _If_ R ever decides to start shipping these mime-types, RKWard is going to get the blame for conflicting names, I'm afraid. i hope this is solved for good now. the hint to libreoffice.xml was useful and led me to the vnd.* files. i'll try and test if this and the protocol handler also works on OS X. can you check that on windows? and if you click on an *.RData file, you're asked *once* whether the workspace should be saved -- after that, the current worspace is just silently replaced with the content of any other RData file you click. I changed that a bit, and yes, it might be buggy, but I think you should find, the behavior is now: - If a workspace has just been loaded, and not been touched, don't ask whether to save it before quitting / replacing it. - If you touch some object in between, you should be prompted, again. right, i missed that part -- i was just baffled that rkward switched from one workspace to another without asking, and i was wondering what that would do to one's data if you accidentally clicked on a *.RData file... but that's a good solution now. - Now as to why you're prompted for the initial - probably empty - workspace: It's that .Random.seed that gets created some time in the middle of starting up. Did not think up a nice way to cope with that, yet. actually, that is something that has always annoyed me a bit: i start RKWard and want to *open* a previous workspace, but the first thing i get is a question whether to *save* the workspace. good thing if that was gone. do we have to care for that single .Random.seed object when one wants to open another workspace anyway? single objects can't be added to the workspace this way either. there should probably be two methods for handling *.RData files: complete workspace or individual R objects, True. KDE knows this as service menus, i can try to write an according *.desktop file as well. then you'd have to actively open the file via right click. that would need another option for the rkward binary. alternatively, RKWard could ask you how to deal with the input: replace current workspace or add all objects to the current one. do you know whether there's a difference between *.RData files containing saved workspaces and saved R objects? if there was, we could add a magic section to the MIME type, which would cause the first bits of a file to be read to get its type. and you should always be asked before your workspace is wiped. Really? no, its fine as it is (except maybe for the initial workspace). viele grüße :: m.eik -- dipl. psych. meik michalke institut fur experimentelle psychologie abt. fur diagnostik und differentielle psychologie heinrich-heine-universitat d-40204 dusseldorf signature.asc Description: This is a digitally signed message part. -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

Ah, yes, that sounds much better! i'll try and test if this and the protocol handler also works on OS X. can you check that on windows? Will try to remember. I have an inkling it's going to require adding it to the registry, though... actually, that is something that has always annoyed me a bit: i start RKWard and want to *open* a previous workspace, but the first thing i get is a question whether to *save* the workspace. good thing if that was gone. Yes. I'll try to come up with something. do we have to care for that single .Random.seed object when one wants to open another workspace anyway? No, but how to tell it apart for other, more interesting objects, reliably. I think the solution will have to involve something like marking the workspace as clean, at an appropriate point in the startup sequence, and then only asking to save, if it was modified after that. alternatively, RKWard could ask you how to deal with the input: replace current workspace or add all objects to the current one. do you know whether there's a difference between *.RData files containing saved workspaces and saved R objects? if there was, we could add a magic section to the MIME type, which would cause the first bits of a file to be read to get its type. I don't think so. ?save.image says: save.image() is just a short-cut for ‘save my current workspace’, i.e., save(list = ls(all = TRUE), file = .RData). Even if you could tell how it was saved, that still doesn't tell, reliably, how you'd like to use it. In general, there are three options: - Replace current workspace - Merge with current workspace (potentially overwriting objects) - Import into a sub-environment And then, if a .workplace-file exists to go with that, for the first two, there's also the question, whether to load that, and if so, whether to close all other windows first... So - a whole lot of options, really. I guess a plan could look like this: In the menu, provide two actions: One is the current behavior. The second (perhaps called Import Workspace...?) would offer all applicable choices. If there is a request to open a workspace file in a running session (from RKWard's own filebrowser, or externally), and the current workspace is not empty, use that second action, too.
