I'd agree; that is probably the most efficient thing to do with only half a
dozen binary variables and a single condition.
A way of going about it for a more complex case might be to

Given that clarification, I'd just generate the full set and remove
the ones you aren't interested in, as in:
scenarios <- expand.grid(A = c("pass", "fail"), B = c("pass", "fail"), C =
c("pass", "fail"), D = c("pass", "fail"), E = c("pass", "fail"), F =
c("pass", "fail"))
scenarios <- subset(sc
From what I can tell, the simplest way is to
First generate all the combinations
Then exclude those you don't want.
Here's an example, with only three variables (D, E, and F), that excludes those
where E and F both fail

> X <- expand.grid(D=tmp, E=tmp, F=tmp)
> X <- sub
Thank you for pointing that out, I realize not only did I use the wrong
language but I did not describe the situation accurately. I do need to
address the situation where both variables E and F actually pass, that is
the majority case, one or the other can fail, but there can never be a
situation

How about this?

I have 6 variables, (A,B,C,D,E,F) that can either pass or fail (i.e., true

I can get a table of all pass/fail combinations with this:
