[R] understanding the FUNCTION function

[michaelyb]

Ista,

Since you seem to know your stuff very well, how would you get 120 out of a
function that gives you the factorial of 5, without using factorial(5)?

> Meanwhile, look at this example instead: 
> fac<-function(x){a<-1 
>                 for(i in 1:x){ 
>                 a<-a*i 
>                 print(a)}} 

gives you 120, but you cannot access it after the end of execution.
