[R] Extract data from edit chart

[Gabor Grothendieck]

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)
