Dear Fazal
I think part of your problem can be addressed with merge

I have two separate tables for the genes which contain the Unique Subject ID in one column and information on whether the gene is mutated or not in that particular subject (M, N/M) in another column called (Condition). I want to make a loop which can read the Unique Subject ID from my data frame, then look up for the same ID in the two tables and depending on whether the gene is mutated (M)/not mutated (N/M), inserts Yes like emoticon / No (N) in the appropriate gene column (Gene1/Gene2) for each Subject ID.
