hi, if you remove columns from a data.frame (e.g., by overwriting it with an empty data.frame) which is opened in RKWard's data editor at the same time, you are asked if you would like to recover that data. try this:
myTest <- data.frame(a="test", b="test") # after this, open myTest in the data editor # keep it open and overwrite the object myTest <- data.frame() # you'll be asked to recover both variables "a" and "b" while this is generally a nice feature, it can be quite nerve-wrecking in cases where you want to recreate large objects from scratch and happened to forget to close the editor tab... i haven't found a way to deactivate this, and there doesn't seem to be an option to check something like "don't ask again". i then usually spend a few minutes clicking "no" a hundred times. i don't know how RKWard handles this, but i think it would be best if you were not asked one variable at a time, but once for the whole object, presenting some kind of list of variables which were removed and could be checked to have them recovered. but at least a "don't bother me gain" checkbox or a "say 'yes' to all changes to this object" button would be nice ;-) viele grüße :: m.eik -- dipl. psych. meik michalke abt. f"ur diagnostik und differentielle psychologie institut f"ur experimentelle psychologie heinrich-heine-universit"at d"usseldorf
