I see some code in R to attach finalizers to external pointer references (Register[C]Finalizer). Anyone have an example of how to code the finalizer? R_RegisterCFinalizer accepts a C function, but I can't see how to get it to operate on the pointer, since the pointer is not passed to the function when its called. RegisterFinalizer takes an R closure, but how is it called from R (tried

Hi, I am trying to install R 1.4.1 on and SGI using 64 bit. When I configure I get... R is now configured for mips-sgi-irix6.5 Source directory: .

Prof. Tierney, Thanks very much for the info. Why does the loop work if I move the assignment out of the condition? E.g., the following works: i <- 0 while(i < 5) { i <- i + 1 if(i < 3) next print(i) } Regards, Andy > -----Original Message----- > From: Luke Tierney [mailto:luke at nokomis.stat.umn.edu] > Sent: Tuesday, October 02, 2001 3:36 PM > To: Liaw, Andy

Does anyone know what exactly S_alloc() does? (Yes, it's porting time again ...)

I'm curious if any of the core R developers have considered the possibility of hosting R (v2?) on the parrot common runtime environment. Perl6 will generate byte-code for parrot, as will some future version of python. I can imagine both drawbacks and advantages. Some advantages would be fast byte-code execution and freely mixing perl, python and R modules. Anyone looked into this? Tim

Can a C function wrapped with .Call return void? Or must it return a valid SEXP? Thnx. Tim -- Timothy H.

I wonder if it was possible (and desireable) to implement means to protect data objects (and functions) from overwriting them. So for instance: > x <- 5 > protect(x) > x <- 8 Error: x is read only Or would that be against the philosophy of R to be compatible to S?! Just a RFC ;-) Yours, Christoph. ps. Your probably know the situations that let you think of such a feature

luke's demonstration of external references, at www.stat.umn.edu/~luke/file_0.0-0.tar.gz (accessible through the developer page) causes a segfault on solaris 2.8 as soon as library(file) is attempted. it runs fine on RH 7.2. the segfault on solaris occured for R 1.5.1 and 1.6 (8-25 image) a quick poke at gdb (which i can only get running for R 1.6, though this bug report is for 1.5.1)

Hi! I've been able to configure and make R (1,4,0 linux) except for the gnome support. I've checked all packages and libs mentioned in R-admin.pdf (and by Luke Tierny) to make sure that I have them and even using the following: ./configure --with-gnome --with-gnome-includes=/opt/gnome/include --with-gnome-libs=/opt/gnome/lib --with-libglade-config=opt/gnome/lib I still get: R is now

Hi, R-1.4.0 on ES40 under OSF 5.1.

I like Thomas' example. Kurt can you include it in the FAQ. Recently I have been doing a lot of programming that has required either optimization or zero-finding. Unfortunately most of the functions need some arguments to be optimized over and have other parameters that depend on the data but are fixed with respect to optimization. With R scoping rules this is a trivial problem; simply

Hi, all. I'm running R on a beowulf system, with software that can take a list of single-processor jobs and parcel them out over the system. (In case it's of interest, they're dual pentium 866 machines connected by fast ethernet.) The administrators of the system found that I was causing a huge load on the file server, and when they investigated it turned out that each process was

I was trying to use closures within a library as follows - foo <- local({ # some code creating local variables function() { # uses the local variables created above }) It did not work because call to do_libfixup in library replaces all the closure environments by the global environment. One way around this would be to do the replacement only for closures that have the same

This is just an idea for comment. Perl6, the upcoming version of Perl has separated out the runtime into a virtual machine called Parrot. There are already several small languages (one is C-like, one is Java-like and one is BASIC-like) that target Parrot and given the popularity of Perl its likely that others may attempt to target it too. If R could interface easily with Parrot then it might be

This situation arose in a computer practical this morning. A student overwrote "c" with a function. This messes up lots of things, but it is difficult to remove the function "c" from the global environment because it is used as a function in both "rm" and "remove". [The solution was to reassign "c" as a number, and then remove it.] Would it be

Can Luke Tierney's recent S-new post on scoping be included in the R FAQ? I'm just going through my package and eliminating a few instances of "eval" as I hadn't realized the dangers. I noticed that one way I've used eval is for prompting, as in n <- eval(parse(prompt="Enter the number of singular values to use: ")) I presume this is not too dangerous, but

Dear R-devel, I've run into this problem that when I hit c-c to interrupt a command or computation, the R session just ends. The info: R-1.4.1 compiled from source on Linux Mandrake 7.1. Dual P-3 Xeon with 2GB ram. 1. Compiled R with link to Intel Math Kernel Library (for fast BLAS), which needed pthread. C-c at the R prompt ends the R session. 2. Compiled R with link to (threaded)

Byron Ellis has been making some progress on a hdf5 library for microarray data (and any other thing you want to put in there). In doing so some issues have arisen that are of more general interest. 1) hdf5 supports annotation (through comments) so it would be nice if the comment function in R became generic. I think this is backward compatible and basically not really an issue of any
