Hi Alfredo, Short answer is no. As en example, consider the following:
# example require(boot) x <- c(4, 4, 4, 3, 2, 4, 4, 3, 6, 2) res <- boot(x, function(v, index) mean(v[index]), R = 1000) res str(res) More information can be found under ?boot (after loaging the boot package) as well as in [1] and [2].
