Hi,
I need your help :: what i the meaning of this error message"Missing value where
true / false needed??"
Hi Inchallah,
This usually happens when you have a conditional (if or while) statement
like this:
if(var81 == 0) { ... }
while(var73 > 0) { ... }
ifelse(var13, ...)
If one of the variables resolves to NA, you will get that error message.
