While loop working with TRUE/FALSE?

Hi R users,

is there any possibilty that a while loop is working like that:

z <- c(0,1,2,3,4,5,6,7,8,9)
r <- 7

   while(w == T) { 
        for ( i in 1:10 ){
                w <- r == z[i]
                print(w)  
        }
}

What problem are you trying to solve? In R, loops should generally be
avoided, and you have much simpler syntax for most cases.

The loop should stop if w == TRUE

Your while loop stops when w == FALSE here. Anyway, it won't run since w
isn't set the first time the condition is tested. And I really don't see
why you have two embedded loops here.


Cheers
