[R] 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

Re: [R] Extract data from edit chart

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
