your example works fine for me:
> repeat {
+ cat("Please, enter a number (Zero ends)")
+ n<-scan(n=1)
+ if(n==0)break
+ i<-("The number is odd")
+ p<-("The number is even")
+ if (n%%2==0)
+ p else i
+ }
Please, enter a number (Zero ends)1: 1

Please, enter a number (Zero ends)1: 2

Please, enter a number (Zero ends)1: 3

Please, enter a number (Zero ends)1: 0

now if you want the answer, you have to use print:
> repeat {
+ cat("Please, enter a number (Zero ends)")
+ n<-scan(n=1)
+ if(n==0)break
+ i<-("The number is odd")
+ p<-("The number is even")
+ if (n%%2==0)
+ print(p) else print(i)
+ }
Please, enter a number (Zero ends)1: 1
