Hello,
         I have a dataframe with a column 'col' of expressions of the form
2*3+4*5+6*7 and substrings thereof.
Now
>eval(2*3+4*5+6*7) is ok.
But I want it done on that column... nothing seems to work
Even
> cil <- dataframe$col
>eval(cil[1])
2*3+4*5+6*7

I want the elements of the column evaluated.

Thanks,
