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.
Right. So learn to avoid depending on `print` for its side-effects:
fac<-function(x){a<-1
for(i in 1:x){
a<-a*i
}
return(a)}
fac(5)
[1] 120
