R help - Mar 2009 - Help with 'boot'

Hi,

I'm wanting to test for a difference in medians between 2 groups using
resampling methods. I found the boot package, but don't really understand
how to write the 'statistic' function required as the 2nd argument for
the
bootstrap test.

Thanks if you can help,

Paul

Hi Paul,
I struggled with the boot package too, and I found this help link very 
useful:
http://www.mayin.org/ajayshah/KB/R/documents/boot.html
"Getting started with the "boot" package in R for bootstrap
inference".
I hope you'll find what you need there !
The second argument for the bootstrap test just tells R on what you want 
to bootstrap on. Just try the examples in this tutorial...
