[Rd] namespace magic

[Roger Koenker]

I'm confused about name spaces.  This morning I installed the
boot package because I wanted to look at bca.ci.  So I did
library(boot), but then I had,

> bca.ci
Error: Object "bca.ci" not found

I had a look in the boot R directory and bca.ci was there as expected.
So then I took a look at the NAMESPACE file for the boot package and saw
that bca.ci wasn't exported.  I tried

example(boot.ci)

and this worked fine including computing the bca.ci version of some
intervals.  Finally, I read the section on name spaces in Writing R
extensions, which was very helpful but still didn't answer my basic
question:  how is it that bca.ci is not loaded and still available
to do the example?  And why not export bca.ci and friends?
