Usage of OCaml/R binding.
Hello. I've been pulling together a Debian package out of Maxence Guesdon's OCaml bindings for R. Will be available from my website as soon as I get my router to obey me. Here's Maxence's bindings: http://pauillac.inria.fr/~guesdon/ocaml-r.en.html The purpose of this software is to access R from OCaml programs.

OCaml-R and xts works!
Hi. I've managed to make a *very* simple wrapper around the xts library for R into OCaml. (Need to be downloaded from CRAN for OCaml users, but I expect other wrapping to be fairly similar...). The good, good, good thing (from my humble point of view) is that all loading is done statically: Loading the R interpreter is done statically. Loading the xts library is done statically... etc...

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

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:~$

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

R_NilValue and segfault.
Hello. I've been trying to wrap up the R_NilValue into OCaml-R. I nevertheless get a segfault. As I gathered, R_NilValue is declared in Rinternals.h: > /* Special Values */ > LibExtern SEXP R_NilValue; /* The nil object */ > LibExtern SEXP R_UnboundValue; /* Unbound marker */ > LibExtern SEXP R_MissingArg; /* Missing argument marker */ So, in my r_data.c

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/

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.

Stop packages and datasets to be loaded on startup.
Hi. I would like to know how to start an embedded R session, and avoid datasets and the standard library packages to be loaded on startup. I've been looking at littler's code (so this is partly a question to Dirk Eddelbuettel...): > /* We don't require() default packages upon startup; rather, we > * set up delayedAssign's instead. see autoloads(). >

R strings, null-terminated or size delimited?
Hello. I've been looking at vecsexps for my binding. Concerning strings, I'm wondering: are they supposed to be null-delimited? Are they delimited by the info in the SEXPHEADER macro in Rinternals.h? Basically, what are the macros or functions to access the values of the vecsexps? I'm thinking of CHARSXPs and INTSXPs for the moment... All the best, -- Guillaume Yziquel

R_tryEval for OCaml-R.
Hello. I'm currently working on the OCaml-R binding allowing to call R code from Objective Caml. As Objective Caml is a functional language, I'd like the binding to be as 'functional' as possible. Specifically, this means that I'd like using the R_tryEval function and all related entry points in libR.so. I've had a look at R-exts.pdf, but R_tryEval is not documented.
