I'm trying to find a function that can replace multiple instances of values
or characters in a vector in a one step operation. As an example, the
vector:
x <- c(rep('x',3),rep('y',3),rep('z',3))
> x
[1] "x" "x" "x" "y" "y" "y" "z" "z" "z"
I would simply like to replace all of the x's with 1's, y:2 & z:3 (or other
characters).
i.e:
> x
[1] "1" "1" "1" "2" "2" "2" "3" "3" "3"
Of course, I'm aware of the replace function but this obviously gets a
little unwieldy when there are :
x<-replace(x,x=='x',1)
x<-replace(x,y=='x',2)
x<-replace(x,z=='x',3)
but I can't figure out how to do it in a one stop operation. My real needs
is more complex obviously. This is one of those seemingly simple
r-operations that should be obvious but I'm coming up empty on this one.
Thanks for the help.
