[R] independent bootstraps for difference of means

[Roger Peng]

This question is for users of the `boot' library.  Can anyone tell me how
to bootstrap the difference means for two independent samples using the
boot() function?  For example, say I have samples x and y and I want to
bootstrap mean(x) - mean(y) by independently resampling x and y.  

At first I thought I could just do two separate bootstraps and then take
differences, but then you don't get the result in a "boot" object with the
nice print and summary methods.

Seems like a simple job but I can't seem to figure out a way.

Thanks,
