What are you trying to do? boot does the resampling for you so you should
pass the statistic that you want calculated on the resamples. Read the
helpfile regarding the format of the statistic. It should take two
arguments, one of which is a vector of indices specifying the resample.

shows a problem and tell me what I am missing. As you can see, the "blocks"
argument is passed corectly, while "m" is not.
