Subject: 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:
> abc<-data.frame(Parameter=c("a","b","c"),Lower=c(" ")
,Upper=c(" "))
> par<-edit(abc)
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)
> par[1,2]
[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!!
