How to find common elements from multiple columns. say i have 20 columns(A,B,C...) & each column consists of number of elements. What i need is to find out common elements of column A in the rest of the remaining 19 columns & vice versa for other columns B,C..... & frequency
Could you please provide some input in the form of a table and the R code on what you have tried so far?

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