[R] Printing values within a function

[Gabor Grothendieck]

f <- function(x) print(2*x)
g <- function(x) cat("the value of twice x is", 2*x, "\n")

Subject:   [R] Printing values within a function 

 
This is probably a really stupid question, but how do I print the value of a
variable within a function? Of course in normal command-line mode I just
type the name of the variable, but how do I have this value exported within
a function?
