definitely! this would be a huge enhacement. wouldn't it be almost enough to limit all column types to be the same? this could be visualized by deactivating/greying out all of the "type" row except for the first cell (of course there's some more changes needed internally, to then actually write a matrix()). at a later point, it would be nice if you could seamlessly turn matrices into data.frames and vice versa, perhaps in the context menu you get when right- clicking on the data.frame (e.g., after "enable editing"). visually, this could toggle the greyed-out type row. > - It can be confined to a fixed nubmer of rows / columns. if the special case of one column was suported, you could also use this to edit vectors just the same :-) viele grüße :: m.eik -- dipl. psych. meik michalke institut f"ur experimentelle psychologie abt. f"ur diagnostik und differentielle psychologie heinrich-heine-universit"at d-40204 d"usseldorf
