Could you please provide some input in the form of a table and the R code on what you have tried so far?

I'm struggling to import table here. I used %in% but it compares 2 column at a time. I want to compare all of them simultaneously in single run

You need to post more complete code snippets than just a line to get useful answers.

No need to use all caps. You tagged this "R" meaning you are looking for R based code?
