Full_Name: Jelle Goeman Version: 1.9.0 OS: mingw32, windows 2000 Submission from: (NULL) (145.88.209.33) Hi Everyone, I get very strange results using the function hasArg with the ... function argument. In my own function: > gt <- globaltest(X,Y) > sampling(gt) works fine, but > sampling(globaltest(X,Y)) results in: Error in eval(expr, envir, enclos) : "missing"

According to :https://stat.ethz.ch/R-manual/R-devel/library/base/html/environment.html "If |fun| is a function or a formula then |environment(fun)| returns the environment associated with that function or formula. If |fun| is |NULL| then the current evaluation environment is returned." > environment() <environment: R_GlobalEnv> > environment(environment)

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]]

This is a message for someone familiar with the implementation. Superficially the R code for seq.default and the C code for seq.int appear to be semantically very similar. My question is whether, in fact, it is intended that behave identically for all inputs. I have found two cases so far where they differ, first that seq.int will coerce a character string to a real (via Rf_asReal) whereas

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

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 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 [1]

I have an object with an attribute "tframe" for which there is a generic method print.tframe and also a method print.tframe.default defined in a library. However, when I use attributes(object) I get the message $tframe Error: couldn't find function "print.tframe" It's as if <primitive: attributes> is not looking through the search list? Any suggestions?

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

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 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. The main
