Point well taken --- grid::gpar() is also a good example; I'll make
use of your suggestion in my future coding.

All these solutions appear to be adding on more and more code with
less and less semantics. Result: messy code which is harder to read
and debug.
It seems that the arguments should have p

Hi,
I think I would follow this approach too, using updatelist() from the
reshape package,
updatelist <- function (x, y)
{
common <- intersect(names(x), names(y))
x[common] <- y[common]
x
}
myfunction=function(list1=NULL, list2=NULL, list3=NULL){
list1=updatelist(list(variable1=1
Barry explained your first puzzle, but let me add some explanation
and examples.
tmpfun <- function( a =3 ) {a}
tmpfun()
[1] 3
tmpfun(a='x')
[1] "x"
Inside the function, the value of the argument is whatever the user
supplied. The default is replaced by what the user supplies. There i

Dear R users,
A co-worker and I are writing a function to facilitate graph plotting in R. The
function makes use of a lot of lists in its defaults.
However, we discovered that R does not necessarily preserve the defaults if we
were to input them in the form of list() when initializing the funct
