statment can tacke value in row1 and rows
Hi Hesham, It think you are looking for something like this: truth<-data.frame(G1=sample(LETTERS[1:4],20,TRUE), G2=sample(LETTERS[1:4],20,TRUE)) truth truth$G3<-as.numeric(truth$G1 == truth$G2) truth Note that like quite a few emails produced with Javascript formatting, there are embedded characters that R can't interpret.

(Simply they regulate the other. If element A is in the first group , and it is related to element B in the second group , and element B also in in the first group , and it is related to element A(the same element in the first group) in the second group , we write 1 and otherwise 0.
