Hello everybody,
I am working with the package bnlear, but, probably, error is caused not by
the package itself.
There is a function cpquery() to which I pass argument str2:
str2="(lag1=='s')"
prob.s = cpquery(fitted1,
event=eval(parse(text="(M=='s')")),
evidence=eval(parse(text=str2)))
- Error in parse(text = str2) : object 'str2' not found
fitted1 is a fitted model
But if I put value of str2 directly into function call:
prob.s = cpquery(fitted1,
event=eval(parse(text="(M=='s')")),
evidence="(lag1.M1=='s')")
it works fine.
Does anybody have any idea how to fix it?
PS:
- I used documentation to the package:
http://cran.r-project.org/web/packages/bnlearn/bnlearn.pdf
function cpquery()
- I also trued to use backslashes \' \" - doesn't work too

Best regards,
Alexandr
