Re: [R] Applying a function to a list of arguments ...
Try this:
func <- function(f, ...) f(...)
# e.g.
func(sin, 0) # same as sin(0)
func(max, 1, 2) # same as max(1, 2)

perhaps something like,

Alternatively, if the caller doesn't want to put the args in a list,
your func can do it:
func2 <- function(f, ...) {
do.call(f, list(...))
}
func2(rnorm, n=3, mean=2, sd=3)

[R] Applying a function to a list of arguments ...
How can I apply function f, that I get as an argument as in
func <- function(f, ...) {
.
.
.
}
to a list of arguments list(a, b, c) (eg the ... argument of func above)
in order to obtain
f(a, b, c)
