Well, not directly. :-)
But the help page of mean says that one of the arguments is:

They work for me under Linux and Windows. What does example(deriv) give
you?

Subject: Using Windows API functions
Thanks Professor,
will try to create a wrapper needed to call WIN API functions.
You cannot make use of WINAPI calls from .C (or otherwise in R): it is set
up for _cdecl calls only.
You will need to write some wrapper C code.
And now i'm at loss how to represent the data structure
Dear Ulf Martin,
Thank you for your thoughtful analysis regarding the use of S3 data
frames in S4. I asked the same question (in a more rudimentary manner)
on the r-help list on 30 Nov 2006 and 04 Dec 2006. There were no
replies. If you find a solution, please post.
Best Regards,

ActivePerl has '-x' switch which tells it to skip all lines in the file till
#!.
This allows writing perl scripts in ordinary .bat files.
?shQuote contains a link with the following perl script example:

@echo off
:: hello.bat
:: Windows executable Perl script

Good idea. ruby seems to work the same way. python does too but with
a slightly different definition:
C:\ ruby -h | findstr strip
-x[directory] strip off text before #!ruby line and perhaps cd to directory
C:\ perl -h | findstr strip
-x[directory] strip off text before #!perl line and
This is R revision 40576 compiled with icc/ifort

deriv ## formula argument :
deriv dx2x - deriv(~ x^2, x) ; dx2x

.grad[, x] -
Ouch. It does look like a compiler over-optimization sort of problem.
I presume that is the ix86 icc, with which we have not had much success on
either Linux or Windows. I've just checked x86_64 icc on Linux, and that
is working correctly.

Yes. No such problem with the pair gcc/ifort. I'll try
less aggressive optimization with icc on deriv.c (I
also have to do that for regex.c).

Switching the icc compiler flag from -O3 to -O0 for deriv.c
solves the problem. As I said, I have to do that for
regex.c as well.

Hackish (and maybe expensive; does match.call duplicate the call
arguments?), but maybe
setClass(A, numeric)
setMethod([,
c(x=A),
function(x, i, j, ..., drop=TRUE) {
... %in% names(match.call(expand.dots=FALSE))
})
a - new(A)
a[i]
[1] FALSE
a[i,,]
New to R, sorry if one or either of these is an inappropriate list for a

You can find this info using the function nargs(). I've used this with
S3 classes, and as far as I know it should work with S4 classes too.
See ?nargs for examples.

Thank you for your reply. There is some more information that may help
your reproduce the error.
