Logic sampling in cpquery() relies on handling unevaluated
expressions, so it is a tad fragile in any complex setting (inside
loops and function calls, for example). On its own, the
eval(parse(...)) trick works if you do it in the global environment,
or in relatively simple scripts.
For the simple query you are trying to do, just use likelihood weighting:
prob.s = cpquery(fitted1,
method = "lw")
passing str2 as a list.
