...4*x5*x6*x7*x8) althoug the resulting formulas are the same, or? This fikses my problem, but R still crashes for the large formula. It may be due to stack owerflow, but i guess this can be altered maually?

...+x5:x7+x5:x8 +x6:x7+x6:x8 +x7:x8) -> R does not crash This is the same formula, at least it should be.
