When is the R-3.2.5 binary for Mac OS X likely to show up? Mick Jordan

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 Mick Jordan [[alternative HTML version deleted]]

I am curious if anyone knows of R code where the "{" function is redefined in a useful way. Or "(" for that matter. Thanks Mick

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

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

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

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. Vincent

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)

I was surprised by this: R --interactive -e 'interactive()' bash-3.2$ R -q -e 'interactive()' --interactive > interactive() [1] FALSE > as the command options document says that --interactive should force interactive=TRUE: " When *R* is run in a terminal (via |Rterm.exe| on Windows), it assumes that it is interactive if ?stdin? is connected to a (pseudo-)terminal

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:

I need some help understanding a problem running the tests on the 'digest' package. Initially, I got the message that the 'knitr' package was needed to run vignettes: Running vignettes for package ?digest? Error in loadVignetteBuilder(vigns$pkgdir) : vignette builder 'knitr' not found So I installed the knitr package and all its dependents (?mime?, ?stringi?,
