Question on Code snippet semantics
I came across this code in library.R
package <- as.character(substitute(package))
where package is the first argument to the "library" function.
I've been racking my brains to understand why this is not just an
elaborate (and ineffcient) way to write:
package <- "package"
E.g.
> package <- as.character(substitute(package))
> package

simplify2array edge case
Should simplify2array(higher=TRUE) treat 1 by 1 matrices differently than others?
I expected a 3-dimensional array from all of the following 3 examples, not just the last 2.
> str(simplify2array(list(array(11,c(1,1)), array(21,c(1,1))), higher=TRUE))
num [1:2] 11 21
> str(simplify2array(list(array(11:13,c(3,1)), array(21:23,c(3,1))), higher=TRUE))
int [1:3, 1, 1:2] 11 12 13 21 22

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

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

Tidyverse/dplyr solution for filling values of a tibble/dataframe from a column with a nested list.
Hi experts.
I have a tibble? with a column containing a nested list (<list<list<double>>>? data type to be specific).
Looks something like the following (but in R/Arrow? format):
ID
Nestedvals
001
[[1]](1,0.1)[[2]](2,0.2)[[3]](3,0.3)[[4]](4,0.4)[[5]](5,0.5)
002
[[1]](1,0.1)[[2]](2,0.2)[[3]](3,0.3)[[4]](4,0.4)
003
[[1]](1,0.1)[[2]](2,0.2)[[3]](3,0.3)

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

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.

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

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)
function(x)

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.

vignette/knitr help
I need some help understanding a problem running the tests on the

was needed to run vignettes:

--interactive and -f/-e
I was surprised by this:

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

looks like a Makefile problem:
