[R] Cycling and different xerror values in cp of rpart, which result should I trust?...

[Levent TERLEMEZ]

Dear Users,
Is it possible to get cycling and different xerror scores in cp of rpart while getting the same tree on every run (or am I missing something or understood wrong)? I build it with an old version of R in a Windows VM installed on a Intel based macbook and reuse the same codes with a newer version of R and required packages on an AMD pc installed with standalone Windows. Both Windows are 64bit, which result should I trust, the old one or new one, macbook or pc?

Thanks in advanced,
Levent TERLEMEZ.
