Dear Roman, could you give us the trace given by traceback() ? I suspect the error is resulting from the permutations and/or jackknife procedure in the underlying functions specaccum and specpool.
You can take a look at the package R.huge, but that one is deprecated already. There are other packages around too, but I have no experience with them. You find some more tips here : http://www.matthewckeller.com/html/memory.html This should give you a place to start looking.
