Tena koe Kate This is what I get:
kateDF # A B # 1 67 76 # 2 24 23 # 3 40 45 # 4 10 12 # 5 70 72 # 6 101 90 # 7 9 12 kateDF$C <- apply(kateDF, 1, function(x) isTRUE(all.equal(x[2], x[1], check.attributes = FALSE, tolerance=0.1))) kateDF # A B C # 1 67 76 FALSE # 2 24 23 TRUE # 3 40 45 FALSE # 4 10 12 FALSE # 5 70 72 TRUE # 6 101 90 FALSE # 7 9 12 FALSE Which seems correct. Can't say why you get something different without more details.

However, the function gives me all falses which seems to be a little weird. Even where both columns equal each other. Should that be right? In essence I want to check whether A and B equal other give or take 10%.
