I'm trying to make a function that will output the exponent... so f2(2,2) = 4 and f2(2,3)=8. But I don't want to just use the x^n function, I want to do it another way, and without a recursion. I did the follow code but for some reason it doesn't work. Help please? f2 <- function(x, n) #without recursion { y <- 1 if (n==0) {return(1)} else { if (length(y) < (n+1) { y <-append(y, x, after = length(y)) } else {return(prod(y))} } } -- View this message in context: http://r.789695.n4.nabble.com/exponent-function-help-tp3663943p3663943.html Sent from the R help mailing list archive at Nabble.com.
