Probably feature, How would you enter abbreviations for North America, Noradrenaline, Neil Adams, etc...? On the other hand, it is currently impossible to make a field blank. Actually, the whole edit() interface is a bit of a long-standing bug. It's been with us "forever" (as far as I remember, the spreadsheet interface actually predates data frames in R). It was constructed using very basic GUI elements on Windows and X11, and it never _quite_ did what you'd want it to do. Ideas about how to do better seem to have gotten stuck in indecision about which graphical toolkit to use. The Rcmdr has a data viewer (but not editor) written with the Tcl/Tk interface, which might be a starting point. -- Peter Dalgaard Center for Statistics, Copenhagen Business School Phone: (+45)38153501 Email: pd....@cbs.dk Priv: pda...@gmail.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
