understanding the FUNCTION function
Simply return it like a function is supposed to:
fac <- function(x, loud = TRUE){
a <- 1
for(i in seq_len(x)) { # seq_len is faster and more robust
a <- a * i
if(loud) print(a)
}
return(a)
}
fac3 <- fac(3)
print(fac3) # As desired

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. -- View this message in context: http://r.789695.n4.nabble.com/Using-FUNCTION-to-create-usable-objects-tp4588681p4590549.html Sent from the R help mailing list archive at Nabble.com.
