Hello,
When the confidence interval is the normal CI, the return matrix has
only 3 columns, all other CI's return a matrix with 5 columns. See
section value in ?boot.ci.
So just change
$norm[, 4:5]
to
$norm[, 2:3]
Hope this helps,
Rui Barradas

Dear R-experts,
Here below my R code. Using "bca" in the boot.ci function at the end of my R code works perfectly. Using
"perc" and "basic" perfectly works as well. But using "norm", my R code does not work
anymore.
Is it possible to solve that problem and to make my R code work ?

s<- sample(178:798, 10000, replace=TRUE)
mean(s)
N <- 100
out <- replicate(N, {
a<- sample(s,size=5)
mean(a)
dat<-data.frame(a)
med<-function(d,i) {
temp<-d[i,]
mean(temp)
}
boot.out <- boot(data = dat, statistic = med, R = 10000)
boot.ci(boot.out, type = "norm")$norm[, 4:5]
})
mean(out[1,] < mean(s) & mean(s) < out[2,])
