...trying to do a loop where I should choose a cell of a data frame comparing it with another. The code actually works for the majority of the loop but for some reason it doesn't and I can't figure out why. When I tried to understand why I've noticed this: > dif[11] [1] 118.8333 > linhasUpdate[10,6] [1] 118.8333 > dif[11]==linhasUpdate[10,6] [1] FALSE Even though the values are the same R says they aren't!
