Hello joris,

this is the traceback() output. Hopefully you can make some sense out of it.
Thank you for the tips as well (R.huge looks promising)!

> traceback()
7: vector("integer", length)
6: integer(nbins)
5: tabulate(bin, pd)
4: as.vector(data)
3: array(tabulate(bin, pd), dims, dimnames = dn)
2: table(y[, factor])
1: accumcomp(PoCom, y = PoEnv, factor1 = "HM_sprem", method = "exact")

Cheers,
Roman
