Re: [R] how to view/edit large matrix/array in R?
Le lundi 05 décembre 2011 à 19:01 -0600, Michael a écrit : head, tail and fix commands don't really work well if I have large matrix/array for which I would like to be able to scroll up and dow, left and right ... Could anybody please help me? RKWard has a good data editor, and you can open several objects at the same time in tabs. But it will not probably work if your data set is really huge (here it works very well with a few thousand rows, though). If you need to see a selection of variables in parallel, ordering the variables so that they're next to each other is probably a good solution.

Could anybody please help me? Thanks [[alternative HTML version deleted]] You might look into the RGtk2Extras package and find the dfedit. You could also embed that in some custom GUI to show variables, as you want. The package requires RGtk2, and hence the Gtk libraries to be installed. The data frame editor there can gracefully handle large data sets. __ 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.

Re: [R] how to view/edit large matrix/array in R?
I think what most everyone is getting at is that the visual identification of numeric outliers is an exceedingly difficult task and one we humans are not well evolved for. Rather they are all suggesting you use visual techniques to spot and fix outliers individually. This practice has a long and reputable history in statistics and has been shown to be far more efficient than simply scanning pages of numbers for a single misplaced decimal. In conjunction, I'd also recommend use of the identify() function, which serves just this purpose. If you have so much data that the csv export is unbearably slow it seems unlikely you can check it all by hand. Another, more general, methodology if you are worried about data corruption is to use robust statistics when applicable.

Re: [R] how to view/edit large matrix/array in R?

I meant the manual procedures of exporting and then opening Excel, etc. is slow and inconvenient and unproductive... You may want to use RExcel then. Liviu On Mon, Dec 5, 2011 at 9:38 PM, R.

Rather they are all suggesting you use visual techniques to spot and fix outliers individually. This practice has a long and reputable history in statistics and has been shown to be far more efficient than simply scanning pages of numbers for a single misplaced decimal. In conjunction, I'd also recommend use of the identify() function, which serves just this purpose. If you have so much data that the csv export is unbearably slow it seems unlikely you can check it all by hand. Another, more general, methodology if you are worried about data corruption is to use robust statistics when applicable.
