Capturing Function Arguments
...evaluating the arguments first, then matching.
This makes a lot of assumptions about the function being inspected: no
NSE, no ellipsis, formals don't depend on the body, nothing weird about
the environment of the function...
f <- function(...) {
.makemissing <- function() alist(a=)$a
.ismissing <- function(x) identical(x, .makemissing())
# prepare to evaluate formals
params <- formals(f0)
e <- new.env(parent = environment(f0))
# assign non-missing formals
for (n in names(params)) if (!.ismissing(params[[n]])) eval(
# work around delayedAssign quoting its second argument...

Capturing Function Arguments
I'm wrapping a function in R and I want to record all the arguments
passed to it, including default values and missing values. I want to
be able to snoop on function calls in sourced scripts as part of a
unit testing framework.
I can capture the values fine, but I'm having trouble evaluating them
as if `force()` had been applied to each of them.
Here is a minimal example:
f0 <-

R windows crash (PR#9426)
Full_Name: Robert Denham
Version: R-2.4.1
OS: Windows Xp
Submission from: (NULL) (61.88.57.1)
R gui exits without warning when I run a function which has an argument with a
default that is not found.
This was a result of an error in a function I wrote, but I thought that it
should exit more gracefully than it does. Here is an example:
testfun <- function(aa=aa) {
aa <-

[PATCH V2] x86/AMD-Vi: Add additional check for invalid special->handle
From: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com>
This patch add an additional logic to check for the often case when the
special->handle is not initialized due to firmware bugs.
but the special->usedid is correct. If users overide this using the
command line option ivrs_ioapic, then it should use the value instead.
