How to make this script ask again
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
Read 1 item
Please, enter a number (Zero ends)1: 2
Read 1 item
Please, enter a number (Zero ends)1: 3
Read 1 item
Please, enter a number (Zero ends)1: 0
Read 1 item
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
Read 1 item
[1] "The number is odd"
Please, enter a number (Zero ends)1: 2
Read 1 item
[1] "The number is even"
Please, enter a number (Zero ends)1: 3
Read 1 item
[1] "The number is odd"
Please, enter a number (Zero ends)1: 4

Please, enter a number (Zero ends)1: 5
Read 1 item
[1] "The number is odd"
Please, enter a number (Zero ends)1: 0

Hi,
as an example I have made this script to give the user the answer if a
number is odd or even:
?{
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
}
If you run this script it will only work once, I mean, after it gives you
the answer is won't ask for another number. You need to run the script all
over again. How could I change it in order to make it ask me for another
number without having to run the all script again?
I have tried with the "repeat" but it doesn't work
?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
}
thanks,
Regards,
ADias
