PROTECT and OCaml GC.
Hello. In the writing of my OCaml-R binding, I'm sort of confused when it comes to the use of the PROTECT and UNPROTECT macros. Basically, I have C stub functions that are in charge of calling R for everything. Here's a simple example: > CAMLprim value r_findvar (value symbol) { > /* The findVar function is defined in envir.c. It looks up a symbol > in an environment.

Problem with R math library.
Hello. I've been working on my OCaml-R binding, and I quite pleased to see that it is functional, though far from being perfect or polished. You can find the gitweb webpage and the interface documentation at http://yziquel.homelinux.org/gitweb/?p=ocaml-r.git;a=tree http://yziquel.homelinux.org/topos/api/ocaml-r/index.html I'm having unexpected trouble with the math library, though.

[Fwd: opened symbols in libR.so available.]
Hi. I've patched Dirk Eddelbuettel's Debian package of R, namely r-base, in order to make hidden symbols of the library libR.so available is now available: http://yziquel.homelinux.org/debian/pool/main/r/r-base/ For instance, the mkPROMISE symbol is available: > yziquel at seldon:/usr/lib/R/lib$ nm -D libR.so | grep mkPROMISE > 000000000011f6f0 T Rf_mkPROMISE > yziquel at

Silently loading an R package.
Hello. I've been working an a binding between OCaml and R (i.e. calling R from OCaml, mostly). See below for a taste of it. I'm currently wondering how to load a given R package silently. I tried require(xts, quietly = TRUE) but I still get some ugly output. Is it possible to squeeze off this output on stdout? All the best, Guillaume Yziquel. > yziquel at seldon:~$

Help with OCaml bindings for R interpreter.
Hello. I've made out a Debian package out of Maxence Guesdon's OCaml/R bindings: http://yziquel.homelinux.org/topos/debian-ocamlr.html http://yziquel.homelinux.org/debian/pool/main/o/ocaml-r/ The upstream software itself is on the following page: http://home.gna.org/ocaml-r/ This binding is dynamically linked to the /usr/lib/R/lib/libR.so and to the /usr/lib/libRmath.so libraries.

Segfault in GetNewPage, memory.c.
Hello. I'm still working on my OCaml-R binding and I get a segfault in the GetNewPage() function of memory.c. For the record, the OCaml-R binding seems to work fine with OCaml bytecode. The segfault here is the main issue I have with OCaml native code. OCaml-R can be found on the following links. Source code: http://yziquel.homelinux.org/gitweb/?p=ocaml-r.git;a=summary

2 IPs for an Asterisk server.
Hello. I've been setting up an Asterisk server, and I am now supposed to move it to a different network than the one it was set on. I'd like to give the server 2 IP address: -1- The first IP address is the IP it will have on the LAN, meaning that softphones will register to the Asterisk server using this 1st IP. -2- The second IP is the one that it will use to connect to the remote

problem with location of libraries 64-bit (opensuse)
Dear list, there seems to be a problem with the standard location of R?s 64-bit libs at least under openSUSE. I had two user questions regarding the compilation of rpy2 for 64-bit systems. Personally I don`t know rpy2 but maybe someone on this list can decide if the mistake lies on R`s side or on rpy2?s side or in between. R-devel is installed in these cases, I asked. Latest R-base or

What symbols are loaded when require()ing?
Hello. I would need to know of a programmatic way to get a list of all the new symbols you get when require(9)ing a package/library. I'd like to know how to do that from within R, or with the C API. Pointers to relevant documentation are also welcome. All the best, -- Guillaume Yziquel http://yziquel.homelinux.org/

Installing rpy2 on Red Hat 6
I need to install rpy2 on RHEL6. The version of R in the 6 repos is 3.0, and rpy2 does not work with that version. I installed R 3.3.3 following the directions here: https://oguya.ch/posts/2017-03-18-building-R-on-rhel-6/. But even with 3.3.3 it's still failing. Using pip it fails with: /usr/local/lib64/R/lib/libR.a(CommandLineArgs.o): could not read symbols: Bad value and installing from

Possible bug: How does libR.so find RHOME?
Hi While installing RPy2, I had curious problems which, if I traced them back correctly, have their root in the way that libR.so find the R installation directory. I wonder if this might be a subtle bug that only causes problems when one has several versions of R on one system but then can be very annoying and cause very strange behaviour. It seems to me that libR.so asks the Unix shell to
