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].


Best,

Jorge
