Extract data from edit chart

Dear R users:

I wonder if it is possible to use 
"data.frame" and "edit" to show the 
form like:

parameter   upper  lower
   A 
   B
   C
when I type the command edit(abc), assume
the data.frame named "abc". And then I want to 
extract the number form it, like abc[1,2] 
which mean the upper level of A, to do something.

The following is my example and the warning messages:
,Upper=c(" "))
then, I key in some number(1,2,3...) and close the console.
Warning messages:
1: added factor levels in 'Lower' in: edit.data.frame(abc) 
2: added factor levels in 'Upper' in: edit.data.frame(abc)
[1] 1
Levels:   1 2 3
How can I fix the warning messages?
And can I just catch the number 1 without the value of Levels: 1 2 3 ?
Please give me some comments about this.
Thank you in advance!!

By specifying space like that you are specifying
that the columns be factors.  If you want them
to be character columns use 

abc <- data.frame(Parameter = 1:10, lo = I(""), hi = I(""))

and if you want them to be numeric columns specify something
that is numeric like 0, NaN, Inf, -Inf or something like that, e.g.

abc <- data.frame(Parameter = 1:10, lo = 0, hi = 0)
