[R] build boot object for boot.ci

Hello all,

I have a dataset with several variables v1...vn and five groups f1...fn. For each group I took a subset of the data


and bootstrapped the weighted mean for v1...vn, which worked nicely.


Afterwards I combined all boot.out$t for each group:




Each row of boot is used as input in a model resulting in boot$W.

My idea is to find (bootstrap) CIs for W. Sorry, I'm new to bootstrap (and R...): Does it make sense to treat the Ws like a bootstrapped variable (and calculate e.g. BCa CIs), because only v1..vn
are bootstrapped? If yes, how is a boot object build on the basis of boot$W?

I'm aware that boot() handles strata, weights and complex functions, but I didn't manage to get my model bootstrapped right. Hopefully, I can circumvent turning my
script upside down.
