I am not a regular user of that facility and cannot see that it has
much value over the facilities available in the console.
Nontheless, I can replicate the error, but not the hang behavior on
a relatively current 64 bit R installation run from the 64 bit GUI:
> dput(data2)
structure(list(Id02 = structure(c(1L, 2L, 3L, 3L), .Label = c("1.a",
"2.b", "3.d"), class = "factor"), Area = c(10, 2, 3, 5)), .Names =
c("Id02",
"Area"), row.names = c(NA, -4L), class = "data.frame")
> edit(data2)
# choosing the "+" icon in the edit window results in this message
in the GUI console window
Error in edit.data.frame(data2) :
SET_VECTOR_ELT() can only be applied to a 'list', not a 'character'

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.

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.
