Hi Sundar,

Hm... the new function correctly returns (and prints) dataf but I need to 
return my.data... 
I also thought about returning my.data, but if this would be a large 
dataframe, printing it wouldn't be so nice.
Basically, I would need to somehow silently return the input (modified) 
dataframe.

Also, I now have another related two questions:
1. is it possible to "edit" the contents of a cell when using fix() ? In order 
to change a letter one would have to change the whole string.
2. is it possible to change the width of a column?

Thank you,
Adrian
