Dear Colleagues.
This should be a very common operation and I believe there should be a nice
way in R to handle it. I couldn't find it in the manual or by searching
online. I am wondering if I could ask for some help in this community.
I have 48 csv files; each stores the data for a specific month. The 48
corresponding months are consecutively from January, 2001 to December, 2004.
I name the files A200101, A200102,
.., A200112, A200201,
,etc.
I want to process file A2000101 and store the result to a new file named
B200101, process file A200102 and store the result to a new file named
B200102
etc.
I do not want to manually change a little bit of the code to read a
different file and write to a different file every time. I want the program
to be able to loop through all the files.
My question is, how to loop through the 48 files?
Your help will be highly appreciated!
Best Wishes
