similar to: Standalone C++ application for processing R parser output(SEXP)

Hello, All! I'm new for R-devel list. And I'd like to ask some questions, maybe they will be stuped for the most part of members of the list. I need to call function which is written in C++ from R. My questions are: 1. How should I include libraries (for example, iomanip, sstream, iostream)? 2. Can I use namespace? Thanks All :) Olga

Hi, I am a newbie in LLVM. I am very impressed with this forum and appreciate your help and time. I am trying to include llvm IR parser in my codebase, the way I wanna do is generate llvm's shared object (.so) file and use it in my project. So far I haven't been able to generate correct .so's. When I build a debug build with gmake (have llvm and clang in my sandbox), I get the

I added "plogis" to the derivative table in the development version of R; the patch against yesterday's R-devel src/deriv/main.c is available at http://www.zoology.ufl.edu/bolker/deriv_patch.txt . I pretty much followed the framework of the other symbols; here was my incantation - } else if (CAR(expr) == PlogisSymbol) { - ans = simplify(TimesSymbol, -

I was thinking about running Wine on Interix (the POSIX layer of Microsoft's Services for Unix). There are a few apparent unknows: Would Wine load the .dll.so's? Since Interix uses PE for it's native format (running on Windows, duh), Would Wine load the .dll.so's? Would it reject them being in PE format and having the 'POSIX Layer' attribute set, or could we hack on a

Hi friends, Again i don't know how to pass multiple arguments from php file to r scripts. Please have a look at this link ; it gives a very simple explanation of passing variables from a PHP page to r scipts.Because i have done the same thing.

While considering statically linking against libc++ (and other runtime libraries from LLVM), I rebuilt LLVM 4.0 with -DBUILD_SHARED_LIBS=OFF. There are still some .so's in llvm/lib, and only one of them seems to exist exclusively as a DSO (libLTO). There's also livLLVMLTO.a, but I doubt LTO is used after linking a binary so this just looks odd to an uninformed LLVM outside and not

R community, As you may know, R's iconv doesn't work well converting to and from encodings that allow embedded nulls. For example > iconv("foo", to="UTF-16") Error in iconv("foo", to = "UTF-16") : embedded nul in string: '\xff\xfef\0o\0o\0' However, I don't believe embedded nulls are at issue here, but rather that R's iconv

Hi,all I'm using ubuntu8.04 and I'm installing gold-plugin along with the document of that, After I built the binutils and LLVM with plugin enabling,and I also replace ld with ld-new which supports plugin,I tried to compile a hello world program by this: llvm-gcc -use-gold-plugin a.a b.o -o hello which is similar with the example in the document,it tells me that libLLVMgold.so can not

I whipped up a quick spec to package Zenoss' wmi client and noticed it creates a libasync_wmi_lib.so.0 and libasync_wmi_lib.so.0.0.1 that their python script would otherwise copy during its install routine (obviously I wrote a native rpm section for installation). Anyone know the naming convention associated with so's when they get compiled, what is the .0.1 extra file used for, they are

I would like to see how the matrix multiplication operator %*% is implemented (because I want to see which external Fortran/C routines are used). How can I do so? Best S??ren

Hi there, I'm not that new in Samba, just paused a little while ;) My actual problem is, that I try to setup a FreeBSD Samba Server who should control share access with authenticating users in a win2k ads domain. The 2K Domain is setup correctly (I think so). Now I created three test shares on the samba server after setting up smbb, nmbd and winbindd. Problem now is any time I try accessing

Hi, I've read ?is.unsorted and searched. Have found a few items but nothing close, yet. Is the following expected? > is.unsorted(data.frame(1:2)) [1] FALSE > is.unsorted(data.frame(2:1)) [1] FALSE > is.unsorted(data.frame(1:2,3:4)) [1] TRUE > is.unsorted(data.frame(2:1,4:3)) [1] TRUE IIUC, is.unsorted is intended for atomic vectors only (description of x in ?is.unsorted). Indeed

Hi! I wonder if anyone has experiences of calling other programs from R (i.e., not C or Fortran programs). Specifically I want to call LEM from R and execute it in a loop to process its output in R. Thanks, Tim Liao

Does anyone have a quick-n-dirty context to implement *66 automatic callbacks? I have a few people who like to have no call waiting on their phone (can you really blame them?) It would be nice to have something like *66, and also like 'Camp On', but instead of waiting something like 30 seconds, monitor the channel until it becomes available, then immediately ring back your phone to

Inside of the anyNA() function, it will use the legacy any(is.na()) code if x is an OBJECT(). If x is a vector of POSIXct, it will be an OBJECT(), but it is also TYPEOF(x) == REALSXP. Therefore, it will skip the faster ITERATE_BY_REGION, which is typically 5x faster in my testing. Is the OBJECT() condition really necessary, or could it be moved after the switch() for the individual TYPEOF(x)

I'm trying to figure this out with "Writing R Extensions" but there's not a lot of detail on this issue. I want to write a (very simple really) C external that will be able to take "..." as an argument. (It's for optimizing a function that may have several parameters besides the ones being optimized.) I got the "showArgs" code (from R-exts) to compile and

It's tough to reliably reproduce, but I often get stack imbalance warnings when calling max.col() on non-real/double matrix. The code is conditionally PROTECTing but not incrementing its nprot counter for the eventual UNPROTECT. Pretty sure this would fix (but I haven't tested it): Index: array.c =================================================================== --- array.c (revision
