How to subtract the counter i in for loop?

Use a while loop instead of a for loop. I don't think what you have coded makes any sense, but fighting the for loop over control of the indexing variable is a recipe for failure.

Hi list,
I am writing a for loop that looks like this:
samples<-rep(NA,10)
x <- rep(c(111, 225), 5)
for(i in 1:10){
   If(x[i]<200){
        samples[i] <- x[i]
    }else{
    i=i-1
   }
}

The problem is that the returning vector still contains NA,  I think
the i
in "else" is not getting subtracted.  How should I get it to work?

Thanks,
Mike
