R help - Jul 2005 - definition of index.array and boot.return in the code for boot

Dear R friends,

I am reading the code for the function boot in package:boot in an attempt to
learn how and where it implements the random resampling used by the
non-parametric bootstraps.

The code contains two (apparent) functions - 'index.array'  and 
'boot.return' - for which I can find no documentation, and which
don't even seem to exist anywhere on the search path.  What are they?

Also, if the meanings of those two don't answer my larger question, could
you point me to the code that implements the random resampling?

Thanks very much for your help,

Excellent question.  Try 'getAnywhere("index.array")'. 
It's hidden
in "namespace:boot".  Ditto for "boot.return".
