Hi Fernando, your "poolaccum" class is a list. You can access each element using either [[ or $ (object$listName). In your case, that would be estimator$jack1. If you want the mean by rows, you can do
apply(X = estimator$jack1, MARGIN = 1, FUN = mean) or if you want standard deviation apply(X = estimator$jack1, MARGIN = 1, FUN = sd) Someone more knowledgeable will have to weigh in on the ACE/ICE estimators.
