Question - You are given 6 .csv files in the attached file. You have to write a program, that will let the user select the files, one by one, or at one time. (Hint: You can write a loop and keep adding the frames of interest to a given variable).
Do NOT hard-code the file names. When the program is checked, it will be run on .csv files with different names.
At the top of the program, you can have a number to indicate how many files it can handle. For example, 6 in the given scenario. When your program is graded, it may be checked for 2 or 7 or 3 (any number of) files. So, the grader should be able to change that number, and the program should work for those many files.
The .csv files contain similar data, and the attribute we are interested in is the USERNAME. You have to combine all usernames from all files, i.e.
- read usernames from each file,
- remove any duplicate usernames,
- and then write the new list of unique usernames to a .csv file. (Q2Result_YOUR FIRST NAME.csv)
Whot to Submit:
- A total count of all unique usernames, i.e., how many usernames did you end up with in the new file ?
- Screenshot of the code.
- .R file SEPARATELY in the section listed.
