collaspe into a name

Dear R People:

Suppose I have the following:

z <- sample(1:4)

if(z == 1)
	bx <- x1
if(z == 2)
	bx <- x2

and so on.

There is something that I can do (Maybe with paste and assign)
to get
bx <- paste("x",z,sep=""))
#Not right, but this is the example.

R version 1.2.2 for Windows
Could someone please help?

This sort of question comes up fairly frequently. There are two parts to
the solution
 1. You could do
    bx<-get(paste("x",z,sep=""))

 2. This sort of solution usually means you are asking the wrong question.
It is rare that manipulating R commands as text strings is a good
solution. You would probably be better off with x being a list or array so
you could do eg

     x<-list(x1,x2,x3,x4)
     bx<-x[[z]]
