[R] problem with boot

[Juan Ramon Gonzalez]

Hello R-users,

I'm using the boot's library. I have two questions:

1. I execute for example

                    data<-rnorm(100)
                    boot(data,mean,500)

and I obtain 500 equal bootstrap samples of data. Why?


2. I need to calculate the bootstrap confidence intervals for a statistic,
but when I use the function boot.ci it shows the error message:

       Error in if (!all(rk > 1 & rk < R)) warning("Extreme Order Statistics
used as Endpoi...

What is happening?

Thank you,

Juan
