Surely a simple question, but for me a show stopper:
I want to update a data table file3 which is the result of a merge of data table file1 with data table file2.
File1 and file2 will have new data every week.
In file3 there are a lot of scripts for data analysis stored, so I would like to updata the data in exacly this file3 instead of generating a new outputfile of by merging file1 and file2.
How do I do it?
