Dear R users,
I have a very simple query.
I am using bootstrap (library(boot)). I want to access the std. error in
the results and further generate confidence interval(CI) for n no. of
samples which will give me n values for std. error and CI.

ORDINARY NONPARAMETRIC BOOTSTRAP
Call:
boot(data = int.inc, statistic = med, R = 1000)
Bootstrap Statistics :
original bias std. error
t1* 9245.998 -0.2855912 43.00874
It would be very helpful for if you could suggest me how to access std.
error in bootstrap or generate confidence interval with some other method.
For confidence intervals, see ?boot.ci For the std.error, read boot:::print.boot, and note that this is just the standard deviation of the non-NA samples. Note that 'boot' is support software for a book: please consult it if you need any further help.
