I have files "File1.csv", "File2.csv",.... and "File33.csv". Each of 33 files has a key variable 'date'. I would need to outerjoin these 33 files using 'date' as the key variable. I understand it is a generalization of
B=outerjoin(File1,File2,'Keys', 'date', 'MergeKeys', true)
But I need to understand
(1) how to write a loop to read 33 files from C:\Dropbox (say)
(2) how to write a loop to outerjoin 33 files
(3) how to write a script to save the output file into C:\Dropbox
I will appreciate a code sample.
