Hi, all
is there a built-in function to compare two numbers?
something like following function
cmp <- function(x, y){
value <- 0
if (x > y){
value <- 1
}else if (x == y){
value <- 0
}else {
value <- -1
}
return(value)
}
Not that I know of, but there is an obvious application of sign():
cmp <-function(x,y) sign(y-x)
