The green book tells:"The basic technique is classic :keep it simple ."A long
,complicated expression or function is less fravorable than" a relatively small
computations that combines calls to a few other functions to perform its tasks."
But I don't get the point totally.Can anyone give me an example to make me
understand this rules totally?
ps:
Is it mean that f1 is better than f2? Thank you!
f1<-function(x){
n<-length(x)
s<-sum(x)
m<-s/n}
f2<-
function(x){
m<-sum(x)/length(x)}
