CRAN testing
Is the mechanism by which packages are tested on CRAN described
anywhere? Is it by any chance written in R? The FastR
<https://bitbucket.org/allr/fastr/wiki/Home> team is interested in
running a virtual CRAN where we can test all the CRAN packages on FastR.
Thanks

Redefining {
I am curious if anyone knows of R code where the "{" function is

Building latest version of package
Hi
I have a package which was built using R 1.9.1 and everything worked
fine. I recently upgraded to R 2.0.1 and tried to re-install my package
- and I got:
Error in library(mypackage) : 'mypackage' is not a valid package --
installed < 2.0.0?
So I tried rebuilding it using my new version of R:
R CMD BUILD --binary mypackage
hhc: not found
cp: cannot stat `mypackage.chm': No

R without graphics
Is it possible to configure and build an R without any graphics support.
I..e no grDevices or graphics packages?
I tried "--with-x=no --with-cairo=no --with-grDevices=no
--with-graphics=no"
but it is still building grDevices.
My problem is that I am using experimenting with a compiler that cannot
compile the Objective-C file, qdCocoa.m, and I don't need graphics for
this

identical on closures
I'm confused by this:
> identical(function() {}, function() {})
[1] FALSE
Yet, after loading the Matrix package (which redefines det), the
following is checked (in library.checkConflicts):
> identical(get("det", baseenv()), get("det", asNamespace("Matrix")),
ignore.environment=T)
[1] TRUE
I've looked at the code in identical.c and for closures it

R-3.2.4 Mac/Linux different in < on characters
Linux:
> x<-c("0","1");y<-c("a","-1"); x<y
[1] TRUE TRUE
Mac:
x<-c("0","1");y<-c("a","-1"); x<y
[1] TRUE FALSE
On both systems, LC_COLLATE/LC_CTYPE/LANG are set to en_US.UTF-8
In Java,FWIW, I get the Mac answer if I use String.compareTo and the
Linux answer if I use Collator.compareTo, but

How to change mem-max to no-limit
Hello,
After I limited max memory usage in one domain, how could I reset
mem-max to no-limit?
Besides, I used "xm create -F xxxx.xm" to create a domain successfully.
But when I shut it down, this domain disappear from "xm list". Why that
happened?
Thanks.

sys.function(0)
As I understand
https://stat.ethz.ch/R-manual/R-devel/library/base/html/sys.parent.html
sys.function(n) returns the function associated with stack frame n.
Since frame 0 is defined as .GlobalEnv which is not associated with a
function, I would expect this to always return NULL. However, it does not:
> sys.function()
NULL
> f <- function(x) sys.function(x)
> f(0)

--interactive and -f/-e
I was surprised by this:
R --interactive -e 'interactive()'
bash-3.2$ R -q -e 'interactive()' --interactive

as the command options document says that --interactive should force
interactive=TRUE:

Problem building R-3.2.4
I am trying to build R-3.2.4 on an Oracle Enterprise Linux system, where
I have previously built R-3.1.3 and predecessors without problems. I ran
"./configure --with-x=no" ok. The make fails in src/extra/xz with what
looks like a Makefile problem:
liblzma.a: $(liblzma_a_OBJECTS)
$rm -f $@
$(AR) -cr $@ $(liblzma_a_OBJECTS)
$(RANLIB) $@
What I see in the make log is:

GUK (enhanced MiniOS) released
I am pleased to announce the release of GUK (Project Guest VM
Microkernel), which is an enhanced version of Mini-OS that underpins the
Guest VM virtual machine. Guest VM is an implementation of the Java
platform, written almost completely in Java, running directly on Xen.
Although GUK was developed specifically for Guest VM, it can be used
stand-alone in a similar way to Mini-OS.

Rd problems when converting DVI version
Hi
Running R v2.0 on SuSe linux 8.2.
I'm trying to build a package (which built perfectly on Windows...) on
Linux, and I ran:

I got:
* checking mypackage-maual.tex ... ERROR
LaTeX errors when creating DVI version
This typically indicates Rd problems
OK, there are no problems with my Rd - I got 3 warnings but they were
all expected, and the whole package builds find

I need some help understanding a problem running the tests on the

Also, you can specify a compiler for Objective-C separately and the
manual advises you to do so (to specify Apple's clang).
