[R] How to do a "go to " in a loop in R

[Lisa Wang]

Hi there,

I'm writing a function which involves a loop. What to write in the "?"
place would allow it skips the "for loop" and goes to  "a[i]<-0".
 
 
 a<-b[s>3,]

 if (nrow(a)==0) ?????????????
                 

	for (i in 1:nrow(a)){
  		a[i]<-1
	}
 a[i]<-0
