Hallo Steven
You probably need to be more specific what is your intention. I still wonder what is the real problem you want to solve.
You loaded binary file and it resulted to 2 data frames. So far so good. But now I am lost.
You want to merge info from data frame "desc" to data frame "data"? You can use attr.
You want to make binary file which behaves like the one you get? Use save/load.
You want to do something different? So please explain what exactly.
Cheers
Petr
