I am looking into change the numeric order in the level of the factor 

> x<-c("A","B","C")
> fx<-factor(x)
> fx
[1] A B C
Levels: A B C
> factor(x)
[1] A B C
Levels: A B C
> as.numeric(fx)
[1] 1 2 3
I want to change the order of the numeric into 3 corresponds to “A” level, 2
corresponds to “B” level and 1 corresponds to “C” level

So when I type in 

As.numeric(fx) I  would like to get 

3 2 1 

Your help is greatly appreciated
