Sorry for the delay,
Many Thanks for Mr. David and Mr. Petr
I thinked to use "sort" function to arrange chronologically value by
'date' (without 'date' is colnames) of each variables (DCE, DP).
The solution of David seems to be simple to understand with "unlist"
function.
The solution of Petr seems to be fancy. I did not find document about "I"
argument for aggregate function.
How can know which value for which date?
I will save the reshaping/ordering dataframe for later use.
Many Thanks,
Karim
