Making an if condition variable ?

Thank you all for wisdom :)
Problem is that I change the condition often and then I forget it. I wanted to put it at the beginning of the program with the other parameters so I wouldn't miss it.

I think this a very common pitfall (I know it from own experience...)
and I would say a candidate for a fortune?

In this case - why not use a function instead of the condition?

cond <- function(x){x>0}
and than

if (cond(4)) {...}

might be the easiest in this case?

or, more flexible,

cond <- function(...){x>0}

if (cond(x=3)) {...}
