Tracy,

thanks, this should be fixed in tonight's R.app GUI, so please try the fixed R.app tomorrow.

Thanks,
Simon

Friends:

Here's what's happening. I load an environment with some of my datafiles then invoke edit on one of them for test purposes.

Here's the file structure:

I can add/delete rows using the icons with no problems in the editor. Attempting to add columns with the icons, however, results in this error message:

Error in edit.data.frame(pub09)  :
SET_VECTOR_ELT() can only be applied to a 'list', not a 'character'

Then R shows the beach ball and never resolves the difficulty. And it shows further strangeness: if the edit window is over the console, all text in the console below is erased. I end up having to force quit every time.

This is only a bother; the datafile isn't affected nor the environment. Besides, I usually work on my data in a spreadsheet, then import. Still, if the editor is to be used for classes, I need to find out why this is happening. I'm guessing it is due to character strings in the datafile, but I can't be sure of that given the circumstances.

Model: MacBookPro2,2, BootROM MBP22.00A5.B07, 2 processors, Intel Core 2 Duo, 2.33 GHz, 2 GB
R:  R 2.9.1 GUI 1.28 Tiger build 32-bit (5444)

Hope I've given enough data to make the problem clear.
