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. 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

Hi All, I have a few small questions about the usage of the C findVar( ) function when used in C code called with '.Call'. In my case I create an R function with an argument. This function calls some C code in which I use findVar( ) to retrieve the values from the argument. Ofcourse normally I would just give the values as argument to .Call, but in my project I need to use findVar for

Dear list, I have been using "findVar" (defined in src/main/envir.c) happily and would like to use "findFun". However I have trouble when the name searched cannot be found: while "findVar" returns R_UnboundValue, "findFun" does not (the 4 last lines of "findFun" are copied below). error(_("could not find function

Documentation and other bugs with postscript(): 1. This code crashes R (it asks for a font that isn't there): postscript() plot(0:1,0:1) text(0.5,0.5,'crash',font=6) The bug appears to be in the FixupFont routine in plot.c; on line 236, it checks that the font number is in the range 1..32. Later this crashes PostScriptStringWidth in devPS.c, because only fonts numbered 1..5

I've been inspired to look at the R source code by some strange timing results that I wrote about on my blog at radfordneal.wordpress.com (see the posts on "Speeding up parentheses..." and "Two surprising things...". I discovered that the strange speed advantage of curly brackets over parentheses is partially explained by an inefficiency in the evalList and

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 trying to use the AMI to originate phone calls. I'm trying to call the SIP phone 'zoiper' with the SIP phone 'yziquel'. So, the AMI interaction is: > Action: originate > Channel: SIP/zoiper > Exten: yziquel > Priority: 1 > Timeout: 30 > Context: internal > > Response: Error > Message: Originate failed > > Event:

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:~$

Hi, I'm wondering if this code from the "Writing R Extensions" manual is really safe: SEXP mkans(double x) { SEXP ans; PROTECT(ans = allocVector(REALSXP, 1)); REAL(ans)[0] = x; UNPROTECT(1); return ans; } double feval(double x, SEXP f, SEXP rho) { defineVar(install("x"), mkans(x), rho);

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'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.

Hi all, I am using R-3.0.1 under Linux platform to embed R into my C++ code. I am facing an error while executing more than 1 R-expressions parallelly. I am executing round(X) and abs(X) parallelly on a set of 50 input rows which resulted in segmentation fault after getting the following errors. Error: unprotect_ptr: pointer not found Error: argument to 'findVar' is not an environment

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.

Hello, I'm working with the gam function and due to the amount of data I am working with it is taking a long time to run. I looked at the tips to get it to run faster, but none have acceptable side effects. That is the real problem. I have accepted that gam will run a long time. I will be running gam many times for many different models. To make gam useable I am looking at splitting the work

If I do > example(lm) ... > mycoef <- function(object, ...) UseMethod("coef", object) > mycoef(lm.D9) Error in mycoef(lm.D9) : no applicable method for "coef" which is pretty surprising, as coef has a default method. After a bit of digging, this comes from do_usemethod having defenv = environment where the generic was defined */ defenv =
