match.call() will return the call. merge.zoo in the zoo package
uses it if you need an example. as.list(match.call()) will return
a list.
list(...) will return the ... arguments as a list.
$.proto in the proto package allows one to write p$f where p
is a proto object and f is a function and p$
Thanks for your replies! The will require some study on my part, which is
good: a lot to learn.

Hi. I'm pretty new to R, but I've been programming in other languages for
some time. I have a couple of questions regarding programming with function
objects.
1. Is there a way for a function to refer generically to all its actual
arguments as a list? I'm thinking of something like the @_ array

I'll escalate this to a bug report once I can fully document, but
something is seriously wrong with readBin on non-blocking connections.

Value:
For 'readBin', a vector of appropriate mode and length the number
of items read (which might be less than 'n').

Hello,
In 2006 Jeffrey Horner proposed [1,2] a patch to allow package level
access to the connection API from C code. As I'm involved in a few
packages that would benefit from this exposure, I felt I would warm the
discussion up.
Does this stand a chance of happening ?

Thanks for your interest in this topic.
In the AD community we are used to dealing with essentially arbitrarily complex
computer code. Some Fortran and C activities have looked at applications such
as global climate models and computational fluid dynamics codes for aerospace
design. Fortran
Hi Simon,
thanks for your information, I have tried to set "R_CStackLimit =
(uintptr_t)-1" after Rf_initialize_R,
but i don't know which Rf_initialize_R, because i found several in my source
code. I had tried to set it
in some place, but it still don't work. Strangely, i add "R_CStackL

Martin (see below) gives a good explanation of the difference between AD and
symbolic
differentiations. I'm of the opinion we can use both. However, the real issue
as far
as I'm concerned (from an optimizer's point of view, which may also be that of
ODE and
PDE folk) is that right now none of t
