How to create functions with new "defaults"?

I can't test it right now, but is this ok ?
t.test.new <- function(x, y = NULL,
alternative = c("two.sided", "less", "greater"),

conf.level = 0.95, ...) {
t.test(x, y,
alternative,
mu, paired, var.equal,
conf.level, ...)

You should name the arguments in the t.test call for safety. But just t.test.new <- function(..., paired = TRUE) t.test(..., paired=paired) is all you need, and for example allows formulae to be used.

Hi R!
I attempt to clear my question through this example. We know that the
default functions for "t.test" is
t.test(x, y = NULL,
alternative = c("two.sided", "less", "greater"),
mu = 0, paired = FALSE, var.equal = FALSE,
conf.level = 0.95, ...)
Suppose, I want to create a new function where "paired=TRUE". What is the
simpler way of creating such functions? I did try, but without much
success.
Thanks in advance
