Changing a read-only data frame to read/write

[TzamouranisY@LouisDreyfus.com]

I need to change a data frame from read-only to read-write.
Doing this through the GUI will not do it in my case - it has to be done through code.

Any ideas how to do this?

I tried simple things such as "as.data.frame" and reassigning it to a new name but failed.

Thanks,
