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, -

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 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.

I am occasional getting "Segmentation Fault - core dumped" in R 0.62.3 (I think more often then I did in 0.62.2). I have not been able to do this in any reliably reproducible way yet, but thought I would mention the problem in case some else can isolate it.

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

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

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

I'd like to propose a change to the R language so that calling 'parent.env<-' on a package namespace or package imports is a runtime error. Currently the documentation warns that it's dangerous behaviour and might go away: The replacement function ?parent.env<-? is extremely dangerous as it can be used to destructively change environments in ways that violate

Hi All, I have some questions regarding the R C API. Let's assume I have a function which is defined as follows: R file: myfunc <- function(a, b, ...) .External(Cfun, a, b, ...) C file: SEXP Cfun(SEXP args) { args = CDR(args); SEXP a = CAR(args); args = CDR(args); SEXP b = CAR(args); args = CDR(args); /* continue to do something with remaining arguments in "..."

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

R version 1.0.1 OS RedHat Linux 6.1 In attempting to test for numeric vectors in a data frame, I tried: apply(dataframe,2,is.numeric) and found that it returned FALSE for all vectors whether they were numeric or not. I tracked this to the fact that as.array() was converting the data frame to character vectors, and thought I could solve it by using array(), which preserved the mode of the
