Consider this script (with h5 installed): $ cat test.R library(h5) name <- tempfile() f <- h5file(name) file.remove(name) $ Rscript test.R Error in initialize(value, ...) : cannot use object of class "character" in new(): class "H5File" does not extend that class Calls: h5file -> new -> initialize -> initialize Execution halted $ /usr/lib64/R/bin/R --slave

Hi Dirk, Thanks for the solution. Now I know the work-arounds, but still don't quite get it. Why does R_DEFAULT_PACKAGES has anything to do with library(methods)? If library(h5) works, it should just work, not depend on an environment variable. Rscript is not consistent with R, that's my confusion.

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/

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.

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

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:~$

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.

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

This post is to announce the 0.2 release of OCaml-R. OCaml-R is a binding embedding the R interpreter into Objective Caml code.

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

Hello. I'm currently trying to wrap up data frames into OCaml via OCaml-R, and I'm having trouble with data frame subsetting: > # x#column 1;; > Erreur dans (function(x, i, exact) if (is.matrix(i)) as.matrix(x)[[i]] else .subset2(x, : > l'?l?ment 1 est vide ; > la partie de la liste d'arguments de 'is.matrix' en cours d'?valuation ?tait : > (i)

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

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.

What ? ====== littler - Provides hash-bang (#!) capability for R (www.r-project.org) Why ? ===== GNU R, a language and environment for statistical computing and graphics, provides a wonderful system for 'programming with data' as well as interactive exploratory analysis, often involving graphs. Sometimes, however, simple scripts are desired. While GNU R can be used
