Error in mean.default(data, original, ...) :
'trim' must be numeric of length one
I know that I am missing something

See the help for boot().
The function in the 2nd argument has to be of a special form.
You need to define such a form, as in:
fmean- function (x, i) mean(x[i]) #use data x[] and indices i
and then
boot.out- boot(d, fmean, R=1000, sim='permutation')
