R help - Feb 2004 - 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?

Here are two ways:

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