[R] How to prevent fix() from converting Dates into numeric

[Christian Gold]

Thanks. So there is no solution, other than avoiding fix() and edit()?
What would then be the recommended way to make visible and inspect large 
data.frames (i.e. that are to big for sensibly displaying on the 
console)? Would I need to write the data to a file and open in a 
spreadsheet programme?
