Re: [R] function to set log(0)=0 not working on tables or vectors

Peter, you're right about the error - I had R commander open and used the terminal instead - this makes me miss the error messages. Not that I would have known how to solve it had I seen it :) And yes, ifelse does work. Not sure I understand what the difference is, but thanks! David, I had no id
